Scientific Contacts between Jews and Christians in the twelfth century: The Case of the Book of Asronomic Tables Fundaments by Abraham ibn Ezra, in his Latin and Hebrew Versions

Abstract

This article intends to prove that Abraham ibn Ezra was the author of four different versions of the Book of the Astronomic Tables Fundaments. Two of those versions were written in Latin and the other two in Hebrew. The article attempts to demostrate that this treatise, especially the writing of the two Latin versions, was a special example of Jewish-Christian scientific cooperation in the twelfth century.
