R. Yosef Colon – the Maharik (ca. 1420 – 1480), leading Italian rabbi in the 15th century and prominent Halachic authority. Born in France to R. Shlomo, a descendant of Rashi. In his youth he travelled through various Italian towns, serving as a teacher of young children, and already then began issuing halachic rulings. He served as rabbi of Piedmont, where he established a yeshiva. Ca. 1430 he was appointed rabbi of Mantua. His prominent disciples include R. Ovadia of Bartenura, R. Eliyahu Delmedigo, R. Yisrael Ashkenazi, R. Azriel Diena, and others. The Maharik owned a particularly large library, including unknown anthologies of Tosafot and books of the Rishonim. In general, he mentions more books and textual versions than any other halachic authority.
Responsa of the Maharik was first published after his passing by his disciple R. Chiya Meir son of R. David. At the beginning of the book, the publisher listed "shorashim", a synopsis of each responsum, explaining in his foreword that since most of the responsa branch out to discuss side topics, he decided to pinpoint the main focus of each responsum. In time, the sections of this work were referred to as "shorashim". Several subsequent editions were published, with some variations. The publisher R. Chiya Meir writes that there are other responsa by the Maharik, which he was not able to obtain despite his efforts. Only in the last generation was the book published with the addition of several dozen responsa from a manuscript. Immediately after its publication, the book became a classic halachic work, and several years later, when R. Yosef Karo composed the Shulchan Aruch and based himself on it in many places, the book became one of the pillars of halachic ruling for the entire Jewish people (see: R. Y. Buxbaum, Toldot Rabbenu Yosef Colon VeShitato, introduction to Responsae and Decisions of Rabbi Joseph Colon, Machon Yerushalayim, Jerusalem 1999, pp. 19-49).
