The legend of the 16th-century rabbi, Judah Loew ben Bezalel, who used kabbalistic powers to create a golem that would defend Prague’s Jews from anti-Semitic violence, is widely known. Less widely known is the fact that this story was concocted in the early 1900s by a Canadian rabbi. Yet tales of rabbis creating golems do have a long history, often involving the use of an esoteric work of uncertain origin known as Sefer Yetsirah. (This same mysterious work is the basis of Ethan Dor-Shav’s provocative reinterpretation of Genesis, recently published in Mosaic.)
The first rabbi to consider these stories as a matter of Jewish law was Tsvi Ashkenazi (1656–1718), who spent his childhood in what are now Czechia and Hungary before pursuing study in Salonica—where he acquired the Sephardi title Hakham (sage)—and then serving for many years as the chief rabbi of Amsterdam. Yosie Levine writes:
Hakham Tsvi had learned that his ancestor, Rabbi Elijah of Chelm (d. 1583), had allegedly created a golem using the Sefer Yetsirah.
What is the halakhic status, Hakham Tsvi wondered, of such a man-made creature? On the one hand, not having been born to a Jewish mother, a golem cannot be said to be Jewish. On the other, the Talmud taught that one who adopted a child was considered to have sired that child. And paraphrasing a midrash, he noted that the handiwork of the righteous was likened to their progeny. In the end, he ruled that a golem could not be counted in a minyan.
Levine goes on to consider the debate Hakham Tsvi touched off, and its relevance in the age of artificial intelligence.
