Abstract

Utilizing the 1894 edition of Simplicius's commentary by J. L. Heiberg in the Commentaria in Aristotelem Graeca, and P. Moraux's 1965 edition of Aristotle's De Caelo, this translation continues a valuable project under the general editorship of R. Sorabji that offers English readers access to works by ancient commentators on Aristotle. By comparing pertinent printed editions and manuscripts, Mueller has maintained the highest standards in weighing variant readings. This is evidenced in the 500 notes, which include not only clarifications of and justifications for particular readings of troublesome passages, but also Simplicius's likely sources along with corrections to misinterpretations of the author by later scholars.
