Ruach Chen, philosophical-scientific work attributed to R. Yehudah ibn Tibbon. Cremona: Vincenzo Conti, 1566. On title page: "Second printing".

This work is attributed to R. Yehudah ibn Tibbon, but there is no evidence that he is the true author. Some attribute the work to R. Yaakov son of R. Abba Mari Anatoli, a Provençal scholar, but this attribution also appears to be erroneous, leaving the author's identity unknown. The book has been published in many editions over time.

Signatures and ownership inscriptions on title page: "Purchased by me, Moshe Kohen Rapa" (perhaps R. Moshe Kohen Rapa, a distinguished member of the Casale community, father-in-law of the Rabach – kabbalist R. Binyamin Kohen Vitali); "G-d granted me this too from my grandfather's inheritance, Ben Tzion Carmi".

Dozens of handwritten glosses in Italian, in margins of all leaves of book.
