Tractatus de sphaera, Ruaḥ Ḥen
Manuscript Item Type Metadata
This is one of approximately forty copies of the only known Hebrew version of the Tractatus de sphaera, which was translated as Mareh ha-Ofanim by the Provençal physician and mystic Solomon ben Abraham Abigdor (b. 1384; translation completed 1399). Although less ornate than the thirteenth-century copies in the Schoenberg collection, this manuscript includes three diagrams, the largest of which (shown here) depicts the celestial and elemental spheres. This codex also includes Ruaḥ Ḥen (fols. 12r-22r), a popular thirteenth-century introduction to Aristotelian science, which it attributes to Yehudah ibn Tibon.
