The first work of Jewish art to attract scholarly attention toward the end of the 19th century was the “Sarajevo Haggadah,” a medieval illuminated manuscript from Iberia. It was eventually published in Vienna in 1898. A few years earlier, one of the few surviving synagogues in Spain, a building commissioned by Samuel Halevi Abulafia in Toledo (1356), had been declared a national monument, and since 1910 the site has functioned as a museum. A dramatic turning point in the historiography of Jewish art occurred in 1932, with the discovery of the 3rd-century synagogue at Dura Europos in modern Syria. In the years to follow, numerous other synagogues and illuminated manuscripts were first documented and were later analyzed and contextualized. The late 19th and early 20th centuries also saw the establishment of several collections of Jewish ritual objects. Whereas medieval finds in this field are extremely rare, such collections are relatively rich in early modern objects. Illuminated manuscripts began to appear in Jewish society in the 10th century in the Middle East and around the 1230s in Iberia, France, the German Lands, and Italy. Although numerous ancient synagogues have been unearthed by modern archaeologists, architectural remains from the Middle Ages are extremely sparse. The earliest structure that was still standing in 1938 was a Romanesque synagogue in Worms. Having been destroyed in November 1938 by the Nazis, it was reconstructed by the German authorities in 1961. Other structures were to follow, and the oldest continuously functioning synagogue (from c. 1280) is found in Prague. By the late 19th century, some very few medieval synagogues in Iberia that had passed into Christian hands in the course of the 15th century were still standing. Several archaeological campaigns since the late 20th century have revealed further remains. Significantly more structures survive at various locations in Europe from the Early Modern period. What is described here as works of Jewish art were not always produced by Jews. Hence, the definition of “Jewish art” in the Middle Ages and the Early Modern period does not necessarily or solely depend on any artists’ identities. For the purpose of this survey, Jewish art will thus not be defined by means of its makers, but rather by means of its users. It refers to art not necessarily made by but for Jews, art that thus functioned as fermenter in the formation of Jewish cultures. In many fields of Jewish art, the role played by the preferences of Jewish patrons is still in need of serious attention in modern scholarship.
