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 is the first of two Terra Sacra volumes, which share the aim of changing our understanding of the environmental impact of crusading and colonization in northeastern Europe.
