The First Latin Treatise on Ptolemy’s Astronomy: The Almagesti minor (c. 1200)

This volume presents a critical edition, translation, and study of one of the most important works of medieval science, the Almagesti minor, the earliest Latin commentary on Ptolemy’s Almagest. This summary of the first half of the Almagest incorporated the astronomy of Islamic astronomers and altered Ptolemy’s work to make it accord with the author’s scientific ideals. The Almagesti minor had a profound effect upon astronomical writings throughout the 13th-15th centuries, including the work of Georg Peurbach, Johannes Regiomontanus, and many others.
