Toledaner tablets

The Toledans panels (also tabule toletane ) are of Arab scholars in the 11th century compiled astronomical data collections that used to calculate the positions of the planets , of eclipses and calendar calculations together presented useful tables. The numerous manuscripts that have come down to us have a lot in common , but in some cases the specimens differ greatly due to omissions and additions.

The content essentially goes back to the works of al-Khwarizmis and al-Battani , at times az-Zarqali was also accepted as author or editor. The place of origin is Toledo , which belonged to the Muslim Taifa kingdom of the Dhun Nunids until the Christian conquest in 1085 , which can be seen from the interpretation of some tables.

The Toledaner Tafeln were translated into Latin by Gerhard von Cremona . They were previously known to Raymond von Marseille , who used them in his work Liber cursuum planetarum (around 1140).

Around 1270 the Toledaner tables were superseded by the Alfonsin tables , which were compiled by order of Alfonso X.
