Or Amim, philosophical work by R. Ovadia Sforno. Bologna: Silk Weaver's Guild, [1537]. First edition.

The author,
R. Ovadiah Sforno (d. 1550), was a leading Italian Torah scholar, renowned for his commentary on the Torah. He lived in Bologna, where he served as posek and earned a living as an expert physician. He was probably one of the sponsors (or initiators) of the establishment of the press of the Silk Weaver's Guild in Bologna.

In his philosophical work Or Amim, R. Ovadiah Sforno challenges and refutes the theories of the renowned Greek philosopher Aristotle. He later translated his work into Latin. The Latin edition was also printed in Bologna, a year later, in 1538. This is the first book printed by the Silk Weaver's Guild (and one of the first Hebrew books printed in Bologna).

Signatures and inscriptions to back endpapers and boards, some in Hebrew: "Yokev Beit of Hamburg"; "Yosef son of R. Yokev Beit"; and more.
