This manuscript contains three sections: (a) Sefer Evronot, a work dealing with calculating the leap year along with reckoning holidays, seasons, and their interpretation. This copy, illustrated by Zechariah Shimon ben Jacob, is heavily decorated and illuminated, with both color pigments and pen-and-ink. The detailed folk-art drawings arte marred only by damage to many of the leaves;
(b) rules on writing marriage contracts (ketubot);
(c) a section, written later, containing recipes, and concluding with an acrostic poem.
