The Intentional Alteration of Jewish Manuscripts and the Houston Mahzor

Abstract Books are living forms that must be understood not simply as they were at the moment and place of their creation, but also as they changed through time and space. This article focuses on a little-known medieval mahzor from the Rhineland, currently in Houston, which has been published in only three catalogue entries. It begins by introducing the manuscript and then goes on to focus on what is perhaps its most remarkable aspect: its extensive mutilation. After examining how and why other medieval Jewish manuscripts were intentionally altered, this essay explores the various campaigns that modified the Houston Mahzor and what can be known about the manuscript’s missing texts and images. Reimagining the Mahzor as it once was reveals a richly illuminated manuscript with strikingly unusual images. Studying how it was intentionally altered over time uncovers a range of reactions from its varied audience, Jewish and Christian, German and Italian, medieval and modern.
