German rabbis of the sixteenth century, as Eric Zimmer remarks in his introduction, were not for the most part very distinguished; they published relatively little, and only one of them (H?ayyim ben Bezalel) achieved even moderate fame. Nevertheless, Zimmer has lavished his attention on these forgotten figures—David of Fulda, Abraham Stang Dülken, Isaac Ginzberg, and others—and his thirty years of patient research of manuscript sources (some of which he publishes here) have culminated in this book. The book is less than a complete survey of the topic, and still shows some signs of having been published initially as separate articles and studies. Zimmer presents a series of snapshots, grouped around the theme of conflict; these German rabbis, distinguished or not, did not lack for quarrels.
