This book provides the first publication of the tract Tiferet Bahurim (The Glory of Youth) which was written in the mid-seventeenth century by R. Pinhas Barukh ben Pelatiyah Monselic in Ferrara, Italy. The tract was written as a guide for young men about to marry regarding their family life and their sexual deportment. By analyzing the Tiferet Bahurim Roni Weinstein addresses the following questions: What was the source of the growing interest in sexuality, and controlling juvenile sexuality? How is this tract related to centuries-old Jewish ethical literature, as well as literature in contemporary Catholic Italy? Is the Tiferet Bahurim part of the religious and cultural fermentation of the Counter-Reformation? Finally, did Jewish mysticism and pietism of Kabbalah tradition play a role in the composition of this tract?
