ISLAMIC Astrology And Astronomy

Johannes Hispalensis translated a good number of Arabian sources on astrology, and gives his own

summary of all these works in Epitome Totius Astrologiae (written ca. 1142); he also gives the Indians

and Dorotheos as his authorities for the Mansions, and the meanings are largely in accordance with

Abenragel’s reports. We know that the Yeatses were referred to this book (see The Yeatses and the

Mansions for this and further consideration of mediaeval Latin sources).
