The Islamic astronomical tradition greatly benefited from the many works produced in different ancient cultures, as well as the new empirical and theoretical approaches that led to advancements in various aspects of astronomy. Nevertheless, a significant portion of the history of this tradition, especially its formative period, was lost or remains undiscovered. Avicenna’s addendum to his recension of Ptolemy’s Almagest, which he incorporated into his main philosophical summa, Kitāb al-Shifāʾ, helps recover parts of this otherwise lost history. In the addendum, Avicenna took a historiographical approach and reported the developments in the science of astronomy that occurred from Ptolemy’s time until his own. As such, the treatise also sheds light on the sources that were possibly available to Avicenna. However, because Avicenna did not explicitly indicate his sources, and because the text’s structure is complex and language condensed, analyzing the treatise is a rather challenging task. The present monograph offers a critical edition of Avicenna’s addendum, complete with an English translation and commentary, to assist readers in better understanding and appreciating this valuable contribution to the history of Islamic astronomy.

The Almagest
The Almagest is by far the greatest work in astronomy in ancient times. In a massive series of thirteen books, Ptolemy shows how every detail of the motions of the sun, moon, planets, and stars can be expressed using geometrical models that can be used to compute celestial positions with remarkable accuracy The present selection covers all the essential features of Ptolemy s treatment of the heavens, omitting only more difficult and abstruse matters such as the moon s motion and the calculation of eclipses. In the interest of conciseness, development of planetary theories is restricted to two planets, one inferior (Venus) and one superior (Mars). Ptolemy s text is accompanied by extensive notes and introductions that are aimed at making the book accessible to students encountering Ptolemy for the first time. This edition is designed to provide everything needed for a one-semester course, or it can be a component of a more general course on planetary theory or history of astronomy."
