Abstract:
This paper offers an analysis of the content of an astronomical table by Immanuel ben Jacob of Tarascon (c. 1350), known as Bonfils, preserved in two Hebrew manuscripts. The table lists the meridian altitude of the Sun and the length of daylight for days in a Julian year at four-day intervals for Tarascon and Avignon. It is argued that the entries in this table were computed using the tables of Levi ben Gerson (d. 1344).
