Manuscript copy of a series of ten sermons by Caleb Ben Eliza Afendopolo (1464-1525), a Karaïte scholar. The Karaïtes are the sect of Jews who believe in the existence of a single written Torah (law), the Torah that was given by God to Moses in the year 2448 (of the Hebrew calendar [=1313 b.c.e.]) on Mount Sinai, after the exodus of Israel to freedom from the Egyptian bondage. (The Rabbanites believe in the addition of oral law given by God to Moses, the Kabbalah.) The present manuscript includes the addition of 3 preliminary pages of a later date, in French with some Hebrew, giving the title as "Livre des dix sermons," providing much bibliographical information about the manuscsript. The manuscript itself seems to be complete, beginning with a title-page and ending with a colophon. There are occasional contemporary ink marginalia in Hebrew, and some later pencil marginalia in French.
