Simplicius

The 15,000 pages of the ancient Greek commentators on Aristotle, written mainly between 200 and 600 AD, constitute the largest corpus of extant Greek philosophical writings not translated into English or other European languages. The works in question are not only invaluable as commentaries. They represent the classroom teaching of the Aristotelian and Neoplatonic schools in a crucial period during which pagan and Christian thought were reacting to each other. This series of translations draws attention to their high philosophical interest; but their significance extends far beyond the period in which most of them were written. They incorporate precious fragments of earlier Greek philosophy from the Presocratics onwards, and the subsequent history of Philosophy cannot be understood without them. Aquinas' reading of Aristotle was partly mediated by the commentators, who gradually transmuted Aristotle to make him agree with Plato and ended by turning his God into a Creator and so making him more acceptable to Christianity. In the time of Galileo the commentaries were seen as a repository of ideas alternative to Aristotle's which could be used in the new series, planned in some 100 volumes, fills an important gap in the history of European thought.
