Or Amim, philosophical work by R. Ovadia Sforno. Bologna: Silk Weaver's Guild, [1537]. First edition.
The author, R. Ovadia 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 presumably 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. Ovadia Sforno challenges and refutes the theories of the renowned Greek philosopher Aristotle. He later translated his work to 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).
Faded ownership inscription on the title page: "Yosef… Ascoli[?]".
