The Synagogue

Why this Chapter exists

The curriculum teaches the cathedral and the mosque. It rarely teaches the synagogue.

The synagogue is the central institution of Jewish communal life. It is not a Jewish church, and not a Jewish version of a mosque. It developed from a specific historical problem: how could Jewish communities pray, study, assemble, and govern communal life when the Temple in Jerusalem was no longer accessible, and then no longer standing? To understand Judaism with even rough accuracy, students need to know what a synagogue is, what is inside one, and how it works, just as the curriculum already teaches the cathedral, the mosque, the stupa, and the temple compound.

Where the synagogue came from

Born in the Temple’s shadow, and built for its absence.

The story of the Temple (the First Temple built by Solomon c. 957 BCE and destroyed by Babylon in 586 BCE; the Second Temple built 516 BCE, expanded by Herod the Great, and destroyed by Rome in 70 CE) is treated in its own Chapter: The First and Second Temples. That Chapter covers what the buildings looked like, where they stood, what survives, and what stands on the Temple Mount today.

What matters here is the consequence. With the Temple gone, Jewish religious life faced a structural problem: the central sacrificial institution that had organized worship for nearly a thousand years no longer existed. The institution developed to meet that problem is the synagogue.

After 586 BCE, the exiles in Babylonia could not access the Temple. After 70 CE, the Temple no longer existed. In both periods, Jewish communities required a way to maintain religious and communal life without the central sacrificial institution that had organized it. One answer, whose origins historians still debate (the earliest hard evidence is from Egypt in the third century BCE, and Lee Levine places the institution's emergence in the Hellenistic period rather than the exile itself), was the beit knesset: the "house of assembly," named for the act of gathering rather than for a sacred location. The Greek translation, synagōgē, also meant "assembly." The institution was portable. It could exist anywhere ten Jewish adults could meet.

The synagogue was not designed to replace the Temple. The Temple's central function, sacrificial worship, was suspended, and the rabbis of the post-70 CE generation declared that prayer, study, and acts of loving-kindness would substitute for sacrifice until the Temple was rebuilt. The synagogue became the setting for all three.

The result was one of the earliest portable religious institutions in human history. A synagogue did not require sovereignty, a priesthood, or a single sacred building. It required a community, a Torah, and the act of gathering. That portability helped Jewish civilization remain continuous across Babylonia, Alexandria, Rome, Cordoba, Vilna, Salonika, New York, and every other place the diaspora, the Jewish communities scattered outside the homeland, reached.

Early Jewish art: the visual record

A figural tradition, sustained and influential.

The synagogue is older as an institution than any of its surviving buildings. The earliest synagogues we know of from archaeological evidence date from the late Second Temple period: Gamla in the Golan, Masada, Herodium, and the recently excavated synagogue at Magdala on the Sea of Galilee. Those are first-century BCE to first-century CE examples. But the buildings that kept enough of their interior decoration to tell us what Jewish religious art looked like in antiquity come from a different group. They survive in three regions. In Roman Syria, there is the painted synagogue at Dura-Europos. In Roman and Byzantine Palestine (roughly the 300s to 600s CE), there are mosaic floors at Hammath Tiberias, Beth Alpha, Sepphoris/Tzippori, Huqoq, Ein Gedi, Naaran, Susiya, Yafia, Huseifa, and Khirbet Wadi Hamam. And around the wider Mediterranean, there are the Jewish catacombs of Rome, the synagogues at Sardis in Asia Minor and Stobi in Macedonia, and the Naro/Hammam Lif mosaic in Tunisia. Together, they show a Jewish artistic tradition that was figural, narrative, ambitious, and deeply engaged with the visual languages around it.

Dura-Europos · the painted synagogue on the Roman frontier (244 CE)

The find that overturned a long-standing assumption.

In 1932, an expedition excavating the Roman frontier town of Dura-Europos in modern Syria uncovered the walls of a synagogue, buried since 256 CE and preserved virtually intact; the paintings are dated by inscription to 244 CE. The story of the discovery and the burial is told in this page’s Object Spotlight below. What matters here is what the walls showed.

The discovery completed a reversal that the Galilean mosaic floors, Beth Alpha above all, had already begun. Many art historians had assumed that observant Jews of late antiquity would never have produced an elaborate figural decorative program for a place of worship, based on a particular interpretation of the Second Commandment's prohibition on graven images. The walls of the Dura-Europos synagogue showed the opposite. They depict, in sustained figural narrative, scenes from across the Hebrew Bible: the Sacrifice of Isaac, Moses receiving the Tablets, Moses leading the Hebrews out of Egypt, the Crossing of the Red Sea, scenes from the Book of Esther, the resurrection of the dry bones in Ezekiel, the anointing of David by Samuel, the Ark of the Covenant entering the land of the Philistines. The paintings establish that, at least in this third-century Jewish community on the Roman frontier, the Second Commandment did not preclude figural religious art.

The synagogue's preservation is also a methodological gift. Because the building was sealed shortly after its decoration was completed, and untouched for nearly seventeen centuries, Dura-Europos is the most intact example of late-antique Jewish visual culture that exists. Most of the murals went to the Damascus National Museum, where the synagogue interior was reconstructed; Yale University Art Gallery holds the Torah-shrine niche, further panels and fragments, and the bulk of the excavation's other finds. The remains of the city itself were severely damaged and looted during the Syrian civil war. What we know of Dura-Europos is what is preserved in those collections and in the photographic record produced by the excavation between 1932 and 1937.

Kraeling, The Excavations at Dura-Europos, Final Report VIII, Part I: The Synagogue (Yale, 1956); Steven Fine, Art and Judaism in the Greco-Roman World (Cambridge, rev. ed. 2010); Annabel Wharton, Refiguring the Post-Classical City: Dura Europos, Jerash, Jerusalem, and Ravenna (Cambridge, 1995).

The Hand of God

The earliest Jewish convention for representing divine presence.

One specific iconographic element of the Dura-Europos murals warrants particular attention, because it is both an early Jewish artistic convention in its own right and one of the visual conventions that subsequent Christian and Islamic religious art absorbed and adapted.

Across multiple panels at Dura-Europos, divine intervention is represented not by a figure but by a single hand emerging from the upper register of the painting. The Hand of God reaches down at the moment of Isaac's near-sacrifice. It points toward the drowning of the Egyptians at the Red Sea. It appears in the Ezekiel resurrection panel. In each case, the visual convention is the same: the God of Israel is not depicted; the action of the God of Israel is depicted by the hand alone. The figural prohibition is preserved by representing the divine agent through the smallest possible part, and through the part that, in human iconography, denotes action, authority, and presence.

The convention appears again, nearly three centuries later, in the floor mosaic of the Beth Alpha synagogue (sixth century CE), where a small hand emerges from a stylized cloud at the Sacrifice of Isaac panel. It appears in the Sepphoris mosaic, in a different formal register. Its afterlife ran through Christian art: the León Bible of c. 960 CE, a Christian manuscript, shows the Hand of God in compositions with striking continuity with the Dura paintings, a lineage many scholars read as the influence of lost Jewish models, and it became a standard convention in Byzantine and Western medieval Christian art for depicting divine presence in scenes including the baptism of Christ, the giving of the Law, and the martyrdoms. The earliest surviving examples of the convention inside a scriptural narrative cycle are the Jewish ones.

This is one example of a broader pattern. The visual conventions of Jewish religious art in late antiquity (the figural narrative cycle, the hand-as-divinity convention, the iconography of the Torah shrine, the menorah as visual symbol, the seven-branched lampstand flanked by other ritual objects) were developed inside Jewish communities and contributed to the iconographic vocabularies of the religions that emerged from and beside Judaism. Seen in this order, the convention belongs first to the Jewish visual record of late antiquity, and only later to the Christian and Islamic traditions that adapted it.

Hammath Tiberias · the earliest known Jewish zodiac mosaic (4th c. CE)

Sol-Helios in a synagogue floor.

The Hammath Tiberias synagogue was excavated on the shore of the Sea of Galilee and is dated to the late third or early fourth century CE. Its floor contains the earliest extant version of a composition that would recur in at least seven later synagogues across Roman and Byzantine Palestine. The mosaic is organized into three panels. At the top, a Torah shrine flanked by menorot (the plural of menorah) and ritual objects. In the center, a zodiac wheel surrounding a depiction of Helios driving his sun-chariot. At the entrance, an inscription panel naming the donors in Greek. The figure of Sol-Helios in the central medallion is rendered in full Hellenistic-Roman style: a young god with a radiant crown, his hand raised, holding the orb of the sun. The signs of the zodiac surround him, each labeled in Hebrew. The four seasons, personified as young women, fill the corners.

Why a sun god in a synagogue. The question deserves to be asked directly. Scholars propose several readings, and they do not exclude one another. Sol-Helios may have served as a visual symbol of the orderly rhythms of God's creation, the way the zodiac itself served as a cosmological calendar. Or the Jewish community of fourth-century Palestine, under increasing Christian imperial pressure after Constantine, the first Christian Roman emperor, in the early 300s CE, may have used Sol-Helios as a visual claim on the cosmos, one that set them apart from the new Christian iconography. Or the composition may be, in part, a polemic: a visual argument that the Jewish people, not the new Christian majority, remained the heirs of the Hebrew Bible. Whatever the precise interpretation, the composition recurred across nearly two centuries and across multiple synagogues. That makes it a sustained iconographic choice, not an outlier.

The Hammath Tiberias floor (together with the Beth Alpha, Sepphoris, and Huqoq mosaics discussed below) is catalogued in the Museum, under Mosaics and architectural fragments, with holding locations for each.

Beth Alpha · the most famous Jewish floor mosaic (6th c. CE)

Akedah, zodiac, and Torah shrine on one floor.

The Beth Alpha synagogue was uncovered in 1928 by members of Kibbutz Beit Alfa, a communal farming settlement, who stumbled on the mosaic floor while digging an irrigation channel. Excavation began in 1929 under Eleazar Sukenik of the Hebrew University. The synagogue is small, a 20 × 14 meter basilica building on the northern slopes of Mount Gilboa, in the Beit Shean Valley, but the mosaic floor is one of the most-photographed Jewish artworks of antiquity. A Greek inscription names the artisans: Marianos and his son Hanina, the same father-and-son team whose names appear on the nearby Beth Shean synagogue floor. The Aramaic inscription dates the construction to the reign of Emperor Justinus, probably Justin I (518–527 CE).

The floor is organized in three panels. The northern panel (closest to the entrance) shows the Sacrifice of Isaac in stylized, almost folk-art form: Abraham raises a long knife, Isaac is suspended in mid-air above the altar with his hands bound, a ram is tethered to a tree by a rope, and the Hand of God emerges from a small flame-bordered cloud in the upper center, with the Hebrew inscription "Do not stretch out [your hand]" above. The central panel is the zodiac wheel with Sol-Helios. The southern panel (closest to the apse where the Torah ark stood) shows a stylized representation of the Torah shrine, flanked by two seven-branched menorot, a shofar (the ram’s-horn trumpet), a lulav and etrog (the palm branch and citron of the autumn festival), and an incense shovel, a visual catalog of the ritual objects that connected the synagogue to the destroyed Temple.

What is happening here. The Sacrifice of Isaac, or Akedah, is among the central scenes in Jewish religious thought. Its appearance on the Beth Alpha floor is not isolated; the same scene appears at Dura-Europos (244 CE) and at Sepphoris (5th c. CE), making Akedah one of the most documented narrative subjects in late-antique synagogue art. The presence of Hebrew script ("Yitzhak," "Avraham," and the quotes from Genesis 22) is itself a distinctive feature: most Jews in the region at the time would have known the narratives through oral tradition rather than reading them, and the script functions both as a label and as a visual marker of the building's Jewish identity in a region where Christianity was rapidly becoming the imperial religion.

Sepphoris/Tzippori · the most elaborate Jewish synagogue mosaic ever found

Genesis through Temple ritual on one floor.

The Sepphoris (Hebrew: Tzippori) synagogue mosaic was discovered by chance in 1993, by a parking-lot construction crew at the edge of the Sepphoris National Park. It is the most elaborate and most fully programmatic synagogue floor we have. The building dates to the early fifth century CE, and it is unusual in several ways. Its bimah, the raised reading platform, was oriented westward, not toward Jerusalem. Its narrative program covers Genesis through Temple ritual. And it carries Greek, Hebrew, and Aramaic inscriptions across the same floor.

The mosaic is organized in seven panels running the length of the central aisle. Near the entrance: the angels visiting Sarah (Genesis 18), a band that survives only in fragments. Behind it: the Sacrifice of Isaac. The central panel holds a zodiac wheel with the sun rendered as a rayed disc in its chariot, with no human figure at all, the one known version of the composition that leaves Helios out, and the four seasons in the corners, the signs labeled in Hebrew. It is the most elaborate version of the composition we have. Beyond it come panels showing the implements and offerings of the Tabernacle (the portable tent-sanctuary that preceded the Temple) and the Jerusalem Temple: Aaron, its first high priest, at the altar; the showbread, the loaves set out weekly in the sanctuary; the menorah, the basin, the incense shovel, and the daily sacrifices. The full program connects the Patriarchs (Abraham, Isaac, and Jacob) to the cosmos to the Temple. It threads them through the lived sacred calendar of the community that walked over the floor.

The Sepphoris floor includes Hebrew inscriptions naming each ritual object. Zeev Weiss reads the program as a statement of the promise to Israel and the hope of restoration, and Steven Fine has traced how the synagogue itself took on the Temple's sanctity in these centuries. The floor worked as a visual encyclopedia of a Temple service that could no longer be performed.

Huqoq · the recent excavations

The earliest images of biblical women.

The Huqoq synagogue sits in the Galilee, three miles west of Magdala and Capernaum. Jodi Magness of the University of North Carolina led an international team that excavated it between 2011 and 2023. What the excavation produced has, in Magness's own words, "revolutionized our understanding of Judaism in this period." The synagogue floor is dated to the fifth century CE. That is a period during which Jewish settlement in the region was historically thought to have declined under Christian Roman rule. Yet this floor holds the most diverse program of mosaic imagery yet found in any ancient synagogue.

The subjects range wide, and these are only some of them. Samson appears, one of only two known depictions of him in an ancient synagogue (the other is at nearby Khirbet Wadi Hamam), including the scene of Samson tying torches between the tails of foxes. Deborah and Yael appear, from the Book of Judges, the earliest known depictions of these biblical women. There is Noah's Ark. There is the Crossing of the Red Sea, with Pharaoh's soldiers drowning and being swallowed by fish. There is the Tower of Babel, a zodiac with Sol-Helios, and Jonah being swallowed by a series of three increasingly large fish. And one panel depicts a meeting between a high priest in Jewish vestments and a Greek ruler with war elephants, read by some as the legendary meeting between the High Priest and Alexander the Great, and by the panel's own publishers as a Seleucid-era episode. That panel is the first historical episode, rather than a purely biblical one, ever found in an ancient synagogue mosaic.

The Huqoq finds matter because they document specific facts. Biblical women were depicted. Jewish communities flourished in the Galilee under Christian rule. The iconographic repertoire was wider than the previously known sites suggested. The workshop tradition was sophisticated and well organized. And the excavation is the most thoroughly documented synagogue mosaic find of the modern era.

The mosaics are not in the public domain; images are held by the excavation's photographer and used by permission. To see the finds and read the project's own account of each panel, visit the Huqoq Excavation Project (University of North Carolina at Chapel Hill).

Galilean and Golan synagogue architecture

Capernaum, Bar'am, and the type.

The mosaic floors document the iconographic record. The architecture holds a parallel record. Archaeologists call it the Galilean-type synagogue, best preserved at Capernaum but documented at Bar'am, Korazin, Meiron, Nabratein, Gush Halav, Arbel, and a dozen other sites. The type has its own visual identity: monumental three-doored facades facing Jerusalem, large hewn limestone blocks, flagstone floors, stone benches along the side walls, columned interiors, and carved relief decoration on lintels, friezes, capitals, and architraves. The Capernaum synagogue is sometimes called the "White Synagogue" because its limestone construction rose over a darker, earlier basalt phase. It stands today as the most impressive surviving synagogue of late-antique Galilee.

The relief carving at Capernaum, Korazin, and Bar'am repeats a set of motifs, a Jewish iconographic vocabulary in stone. There are menorot and shofarot. There is the Ark of the Covenant on wheels, a striking image of the portable Tabernacle. There are palm trees and grape clusters, and the Star of David as a geometric motif, long before it became the modern national symbol. Lions of Judah flank the Torah ark in formal heraldic pairs. The amphora appears as a symbol of the oil pressed for the Temple lamps. These are the same motifs that appear on the floor mosaics. The whole material culture is consistent: a community with a developed iconography of its own, working in stone and tessera and paint across a coherent visual program.

The catacombs of Rome: Jewish symbols outside the homeland. Outside the homeland, the visual record of Jewish life in late antiquity is preserved most extensively in the Jewish catacombs of Rome. Six catacombs are documented: Monteverde, Vigna Randanini, Villa Torlonia, Vigna Cimarra, Via Labicana, and Via Appia Pignatelli. Two are currently accessible. Together they contain more than 500 inscribed epitaphs, written in koine Greek, in Latin, and bilingually. That is the largest single corpus of Jewish inscriptions from antiquity outside the homeland. The catacombs also hold dozens of painted chambers decorated with menorot, shofarot, lulavim, etrogim, ritual objects, and the Torah ark. The menorah appears with such consistency here that some archaeologists have made an argument about it: that the menorah's status as the principal symbol of the Jewish people, after the Temple's destruction, was consolidated in the Roman diaspora rather than in the homeland.

The illuminated Hebrew manuscript

A medieval continuation of an ancient visual tradition.

The visual tradition documented at Dura-Europos, Hammath Tiberias, Beth Alpha, Sepphoris, and Huqoq did not stop in late antiquity. It moved into the codex. From at least the tenth century onward, Jewish communities produced Hebrew manuscripts as illuminated and decorated books. They made them in the lands of Islam, especially Egypt, the Holy Land, Yemen, and the Maghreb. They made them in Sephardic Spain and Provence, and in Ashkenazic central and northern Europe, the two great regional Jewish traditions defined later on this page. The forms varied with the surrounding visual culture, but the project was continuous: the Hebrew word, written and ornamented, as the central object of a visual tradition.

The most famous illuminated Hebrew manuscript in the world is the Sarajevo Haggadah, produced in Barcelona around 1350, probably as a wedding gift for a Jewish family with ties to the rulers of Aragon. It opens with thirty-four pages of full-page illuminations of biblical scenes: the seven days of Creation, Adam and Eve, the Cain and Abel narrative, the Lot story, the Sacrifice of Isaac, the Joseph cycle, the Exodus, the Crossing of the Red Sea, and Moses's blessing. Then comes the Haggadah text itself, hand-written on bleached calfskin vellum in the square Hebrew script characteristic of medieval Spain. The book's later life is a story of its own. It was expelled from Iberia with the Jews in 1492 and surfaced in Italy in the sixteenth century. The National Museum of Bosnia and Herzegovina in Sarajevo acquired it in 1894. During the Nazi occupation in 1942, museum staff and a Muslim cleric, Derviš Korkut, hid it. It was hidden again during the Bosnian War in the 1990s. It is now displayed in a climate-controlled vault at the museum, and it was inscribed in the UNESCO Memory of the World Register in 2017.

The Sarajevo Haggadah belongs to a group of about ten surviving fourteenth-century Spanish illuminated Haggadot. The group includes the Golden Haggadah (Catalonia, c. 1320, now British Library), the Rylands Haggadah (Catalonia, c. 1330), the Sister Haggadah (Catalonia, mid-14th century, now British Library), and the Kaufmann Haggadah (Catalonia, late 14th century, now Hungarian Academy of Sciences). All share a common structural feature: a full-page biblical picture cycle before the Haggadah text proper.

Outside Spain, the most distinctive Ashkenazic illuminated manuscript is the Bird's Head Haggadah, produced in the Upper Rhine region of southern Germany around 1300 (now Israel Museum, Jerusalem). It is one of the oldest surviving Ashkenazic Haggadot. Its human figures are rendered with the heads of birds. Scholars have read that stylization in several ways: as a conservative response to the Second Commandment's prohibition on representational images; as a marker of Jewish identity in a region where church rules that followed the Fourth Lateran Council's dress decree (1215) required Jews to wear the conical "Jew's Hat," the same hat the figures wear on their bird-heads; or as a visual device with multiple parallel meanings.

Other major Hebrew illuminated manuscripts survive as well. The Leningrad Codex (Cairo, 1008/1009 CE) is the oldest complete Hebrew Bible, with sixteen full carpet pages in micrographic decoration. The Aleppo Codex (Tiberias, c. 930 CE) is the most authoritative manuscript of the Masoretic Text. The Damascus Crown (Burgos, c. 1260) is an illuminated Hebrew Bible now at the National Library of Israel. The Rothschild Mahzor was made in Florence in 1492. And the Rothschild Miscellany (Northern Italy, c. 1480) is perhaps the most sumptuously illuminated Hebrew manuscript of the Renaissance, with over 800 illuminations.

Micrography

The Hebrew word as visual form.

One visual tradition is uniquely Jewish. It developed inside the Hebrew manuscript culture, and nothing in Christian or Islamic art matches its scale or its binding to a canonical text. It is called micrography: drawing with minute Hebrew script. The script is often the text of the Masorah, the body of traditional notes on the spelling, pronunciation, and accentuation of the Hebrew Bible. Scribes used it to form abstract decorative patterns, geometric carpet pages, architectural designs, animals, plants, and sometimes full figurative scenes. The text is fully legible. The image is built from the words themselves.

The technique is traditionally traced to the Cairo Codex of the Prophets. That book's own colophon dates it to 895–896 CE and attributes it to Moshe ben Asher in Tiberias, though later scholars have questioned both the date and the attribution. Micrography emerged among the Masoretic scribes of Tiberias and Egypt in the late ninth and tenth centuries. They used the technique to record and decorate the masoretic apparatus around the biblical text. From there it spread across the Jewish world. In Yemen it became a particularly developed art in the fifteenth and sixteenth centuries; the British Library's MS Or. 2348 of 1469 patterns Psalm 119 into a Mamluk-style design of mountains and fish. In Sephardic Spain, micrography decorated some of the Catalan Haggadot. And in Ashkenazic Germany and France, the so-called Masorah figurata tradition produced figurative scenes built from biblical and masoretic text.

Micrography answers a particular question: what does Jewish visual art look like when the word and the image are one and the same? A principle runs through all of Jewish visual culture, and micrography embodies it most directly. The text is itself the central sacred object. Ornament does not compete with the text. It is built from it.

What is inside a synagogue

The same essential elements, in every era.

The interior of every traditional synagogue, regardless of era or region, contains the same essential elements. Their arrangement varies; their presence does not.

The Ark (aron kodesh, "holy ark") is the cabinet that holds the Torah scrolls. It is typically built into the wall facing Jerusalem: east in Europe and the Americas, north in Yemen, west in Iran. The orientation is intentional: the congregation faces Jerusalem during the central prayers. The ark is often the most ornate element in the building, with carved wooden doors, an embroidered curtain (parochet) in front, and a crown above. Inside are the Torah scrolls themselves, each handwritten on parchment by a trained scribe over the course of about a year.

The Bimah is the raised platform from which the Torah is read aloud. In classic Ashkenazi practice it stands in the center of the room, and in the Spanish-Portuguese rite at the far end facing the ark. Placing it on a platform beside the ark is a nineteenth-century modernization now common in American synagogues. The reader places the Torah on the bimah, opens it, and chants from it using a system of musical notation called cantillation, a tradition transmitted orally for two millennia.

The Ner Tamid (eternal lamp) hangs above the ark. It is kept lit continuously, day and night, as a deliberate echo of the perpetual lamp the Torah commanded for the Tabernacle and Temple. In ancient synagogues it was an oil lamp; in modern ones it is usually electric, but the symbolism, and the requirement that it never go out, is the same.

The Menorah. The seven-branched menorah was the central candelabrum of the Jerusalem Temple, carried away by Titus's legions in 70 CE, its image preserved on the Arch of Titus in Rome, where it remains today. Rabbinic law forbids replicating the Temple's lamp, a functioning seven-branched metal menorah, so a synagogue's working lamps carry a different number of branches, while seven-branched menorot appear freely as ornament and symbol. The nine-branched Hanukkiah, lit during the eight days of Hanukkah, is a separate ritual object.

The Mezuzah is a small case affixed to the doorposts of a Jewish home. (A synagogue, not being a dwelling, is technically exempt, though many affix one.) Inside it is a small parchment scroll bearing two passages from Deuteronomy, including the Shema, the central declaration of Jewish monotheism. The word mezuzah simply means "doorpost." It is touched in passing, with the fingertips brought to the lips, by many observant Jews.

Seating. In most synagogues, the congregation sits facing the ark, meaning, ultimately, facing Jerusalem. Orthodox synagogues seat men and women separately, divided by a partition called a mechitzah; Conservative, Reform, and Reconstructionist synagogues seat together. In medieval Italian and Ottoman synagogues, women often sat in a separate gallery upstairs.

How a service operates

Ten adults, a Torah, and a weekly cycle.

A traditional Jewish service requires a minyan: a quorum of ten adult Jews. (Orthodox practice counts only men; Conservative and other movements count adults of any gender.) The number ten is derived from a Talmudic interpretation. Without a minyan, certain central prayers cannot be recited, including the Kaddish, the prayer recited by mourners. The minyan requirement is one of the principal reasons Jewish communities have been so densely organized historically: it requires ten Jewish adults to live within walking distance of each other.

The standard weekly cycle of services follows this pattern. Morning service (Shacharit), afternoon service (Mincha), and evening service (Ma'ariv) are recited daily, with the Torah also read on Monday and Thursday mornings. On the Sabbath, sunset Friday to nightfall Saturday, these are expanded and a fourth service, Musaf, follows the Torah reading, and the central event of the week, the public reading of the weekly Torah portion (parashah), takes place during Saturday morning. The entire Torah is read in this way, in one-year cycles, every year, in every traditional synagogue in the world. The cycle is synchronized: with rare calendar exceptions, the same passage is read on the same Sabbath in traditional synagogues the world over.

The service is led by a prayer leader (chazan or cantor). No ordination is required, any knowledgeable congregant can lead, though the chazan has been a recognized communal office since the Geonic period. In larger synagogues, a professional cantor is employed for musical leadership, especially of the Sabbath and holiday services. A rabbi may give a sermon (drash), but the rabbi's central traditional role is not as priest but as scholar, teacher, and decisor of Jewish law. The synagogue service does not require a rabbi to be present at all.

Types and traditions

Three regional streams, plus modern movements.

Jewish religious tradition divides historically into three main regional streams. Each has its own liturgical text. Each has its own melody and ritual variations. Each has its own architectural conventions.

Ashkenazi tradition developed among the Jews of the Rhineland, France, Central Europe, and Eastern Europe. The historical vernacular was Yiddish. The liturgical melody and pronunciation are distinct. So are the cycle of religious poetry (piyyutim) and many ritual customs.

Sephardi tradition developed among the Jews of the Iberian Peninsula. After the 1492 expulsion from Spain, it carried into the Ottoman Empire, North Africa, the Netherlands, and the Americas. The historical vernacular was Ladino (Judeo-Spanish). The liturgical melody differs from Ashkenazi tradition. So do the pronunciation of Hebrew and several ritual practices.

Mizrahi tradition covers the Jewish communities of the Middle East, North Africa, the Caucasus, and Central Asia. That includes the Iraqi, Yemenite, Persian, Bukharan, Moroccan, Tunisian, Algerian, Libyan, Syrian, and Egyptian communities. They are diverse, and each has its own ritual customs. Most North African and Levantine communities absorbed the Sephardi rite after 1492; the genuinely independent liturgical families are the Yemenite Baladi rite, the Romaniote rite of Greece, and the Italian rite.

Modern denominational movements grew up within these traditions in the nineteenth and twentieth centuries. They arose primarily in the Ashkenazi world. Increasingly, though, they reach across all traditions. Orthodox Judaism observes traditional Jewish law (halacha) as binding. Reform Judaism began in early-nineteenth-century Germany. It treats halacha as historically contingent and emphasizes prophetic ethics. Conservative Judaism (in the United States) and Masorti (elsewhere) developed in the late nineteenth century. They retain halacha but allow for historical evolution and modern adaptation. Reconstructionist Judaism was formalized in twentieth-century America. It treats Judaism as an evolving religious civilization. Each movement has its own associated synagogues, prayer books, and ritual conventions. And each regards itself as part of one Jewish people.

Architecture across the diaspora

The institution is constant; the body is local.

One of the most useful exercises for a student is to compare synagogue architecture across regions. The interior elements (ark, bimah, ner tamid, orientation toward Jerusalem) are constant. The exterior frequently mirrors the surrounding civilization's vernacular: Gothic in medieval Prague (the Altneuschul), Mudejar in fourteenth-century Toledo (El Tránsito), classical revival in eighteenth-century Newport (Touro Synagogue), Moorish Revival in nineteenth-century New York (Eldridge Street), Bauhaus in 1930s Tel Aviv. The synagogue is the institution; the architectural body is responsive to local time and place.

This means that walking through synagogues across the diaspora is also walking through the architectural history of every region where Jews lived. The Hurva Synagogue in the Jewish Quarter of Jerusalem's Old City (destroyed by the Jordanian Arab Legion in the 1948 Arab-Israeli war and reconstructed in 2010) is built in the Ottoman-influenced style of nineteenth-century Jerusalem. The Great Synagogue of Florence (1882) is Moorish revival. The Dohány Street Synagogue in Budapest (1859) is the largest in Europe and combines Romantic and Moorish elements. Each is a synagogue, with the same ark, the same Torah, and the same weekly reading; each is also a building shaped by its city.

Several of the synagogues discussed here are explored in greater depth in the Virtual Field Trips collection, where their architecture, objects, and historical context can be examined in place. →

Object Spotlight

The Dura-Europos synagogue, sealed 256 CE.

Look at the wall before you label it. A woman stands waist-deep in a river, lifting a tiny baby from the water; other figures wait on the bank. It is painted in flat, bright colors, the figures outlined and frontal, more like a storyboard than a photograph. The scene is the rescue of the infant Moses, and it is painted directly onto the plaster wall of a room, the way you might paint a mural.

That room was a synagogue, a Jewish house of prayer and study, in a frontier town called Dura-Europos, on the edge of the Roman Empire in what is now Syria. The paintings are frescoes, pictures done on a wall while or after the plaster sets. And here is the surprise that makes them famous: the walls are covered, floor to ceiling, with people: Abraham, Moses, Queen Esther, the prophet Ezekiel, King David, dozens of biblical scenes full of human figures, painted around 244 CE.

For a long time people assumed that the Second Commandment, the ban on graven images, had stopped ancient Jews from making religious pictures of people, that Judaism was a religion of words and never of images. Dura-Europos proves that assumption wrong in the most direct way possible: an entire synagogue, painted wall to wall with figures, by a Jewish community that clearly saw no conflict. You cannot argue with a room.

Look closer at one recurring detail: in several scenes a single disembodied hand reaches down from the top edge, the "Hand of God," a way of showing God acting without drawing God's body. It is a solution to a real problem (how do you picture the divine without picturing the divine?), and the same device would later turn up in Christian art that grew up nearby. The conventions worked out on these Jewish walls did not stay on them.

And the way it survived is its own story. Around 256 CE the town was under siege; to brace the city wall, the defenders packed earth against the buildings along it, burying the synagogue and its paintings. The town fell, was abandoned, and the dirt sat undisturbed for nearly seventeen centuries until archaeologists excavated it between 1932 and 1937. The paintings came out astonishingly intact and were moved to safety, many now at the Yale University Art Gallery. The site itself, back in Syria, was severely damaged and looted during the Syrian civil war. The accident of a siege saved the most complete record of ancient Jewish painting we have; the images outlived the building, the town, and the empire that besieged it.

The disciplines and courses this Chapter naturally supports, for any educator, anywhere.

• World History & Belief Systems: Judaism beside Christianity and Islam, with the synagogue as the comparative anchor.
• Ancient & Classical History: the synagogue’s emergence after 586 BCE and again after 70 CE.
• United States History: immigration-era America through the Eldridge Street Synagogue (1887), with the colonial-era congregations treated in the American Jewry Chapter.
• Art History & Museum Education: Dura-Europos, the Galilean mosaics, micrography, and synagogue architecture across the diaspora.
• Archaeology: the excavated synagogues at Dura-Europos, Sepphoris, and Huqoq.
• Historical Thinking: how one well-preserved find can overturn an assumption, and the continuity of an institutional form across two millennia.
