Nothaft, C. Philipp E., "Medieval astronomy in Catalonia and the South of France: the ‘improved' lunar Kalendarium of friar Raymond (Ramon) Bancal (ca. 1311) and its predecessors", Llull, 38/1 (2015), en premsa.
- Resum
- During the late Middle Ages, one of the most common tasks of astronomers was the calculation of lunar data, such as syzygies and eclipses, which were commonly utilized by practitioners of medical astrology. A little-known early example for this type of work is the Kalendarium for the years 1311 to 1386 ascribed to Ramon Bancal, who served as the Franciscan minister for the province of Aragon in 1326/27. His work is an improved lunar calendar of a type that first took shape around 1290 in response to the obvious shortcomings of the lunar computus used by the medieval Church. This article will analyze the structure and content of Bancal's work and relate it to other calendars in use at the time. In addition, it will present evidence for a Southern French origin of both the work and its author. The article will close with a look at the Tractat de Bahare, an obscure Catalan text on lunar computation according to the Jewish calendar, which can be shown to date from the year AD 1300.
