Tanya Rabbati is an anonymous work on Jewish law first published in Italy, in 1514.
Tanya Rabbati discusses Shabbat and the Jewish Holidays. The work is named for its first word, "Tanya", which is Aramaic for "it is stated in a baraita." It is believed to have been authored by Jehiel ben Jekutheil Anav (full name: Jehiel ben Jekutheil ben Benjamin Ha-Rofe Anav), a 13th-century Rabbinic author, manuscript copyist, and liturgical poet. The work was first published in Mantua, and was re-printed in Cremona, 1565, and later in two other editions.
Shibbolei ha-Leket (Hebrew, "Ears of the Harvest"), the first Italian Jewish codification of Jewish law, is an earlier work that is similar in scope and content, but more detailed and further elaborated. Shibbolei ha-Leket is concerned with the liturgy, the Passover Haggadah, and laws pertaining to Shabbat and the Jewish Holidays. It was authored by Zedekiah ben Abraham Anav, a 13th-century Italian Talmudist. The work was culled from many Rishonim. Anav "systematized his material skilfully, gave it a concise as well as popular form, and judiciously discriminated between conflicting opinions and decisions, giving preference to those that seemed to him true." It is divided into 372 paragraphs, plus appendices and responsa on topics such as circumcision, mourning, tzitzit, slaughtering, inheritance, and interest. An abridged version was published in Venice (Daniel Bomberg) in 1545, and a complete version in Vilna in 1886.
However, other views exist.
The man, a most modest author who didn't want to accept a crown of greatness, but it would become him, would not want it known that he authored this work. However, we have received a tradition from generation to generation that it is Rabbeinu Yechiel, brother of Rabbeinu Yaakov Baal HaTurim. Indeed, within this work it is said more than once "I am the Sofer Yechiel."
However, there is a hand-written notation below this attributing the work to Jehiel ben Jekuthiel Anav.
