The word “Mahzor,” familiar to most Jews as the term used for the prayer book for the High Holidays, means “cycle.” It can therefore be used to describe a book containing any liturgical cycle. Sometimes the term was also used to describe a text created in codex = book form, as opposed to a traditional Jewish scroll.  

The Mahzor Vitry is an 11th-century composition by Rabbi Simcha of Vitry (just south of Paris), a disciple of Rashi, which incorporates texts and directions pertaining to daily prayers, as well as prayers for the holidays and other special days on the Jewish calendar. It also includes liturgical poems, descriptions of messianic times, and legal sections on marriage, holidays, and ritual slaughter, among other topics. The work is the earliest comprehensive record of the practices of Jews in Ashkenaz (at the time, northern France and the Rhineland). 

This manuscript, completed in 1204 is the oldest, most complete surviving manuscript of this work. 

The scribe of this manuscript was very skilled, writing a dense but very clear text. Like other scribes, he understood that a sacred book—even one with a legal focus—should be beautiful, so he often enhanced the page by creating eye-catching patterns with tiny Hebrew words (micrography), as in the “checkerboard” on the page you see here.
