Simplicius' Commentary on Aristotle

Simplicius wrote commentaries on Aristotle that were unprecedented in their size and detail. He used them as an opportunity to record not only the ideas of previous commentators, especially Alexander of Afrodisius. His writings are a candle lit against what he sees as the encroaching darkness of Christianity. Simplicius was horrified when a Christian named John Philoponus criticized a fundamental tenet of Aristotelian philosophy.
