  Philoponus’ oeuvre comprises at least 40 treatises on diverse subjects such as grammar, logic, mathematics, physics, psychology, cosmology, astronomy, theology and church politics; even medical treatises have been attributed to him. A substantial part of his work has come down to us, but some parts of it are known only indirectly through quotations or translations into Syriac or Arabic. Although his fame rests predominantly on the fact that, even within some of his commentaries on works of Aristotle, he initiated and in fact anticipated the eventual liberation of natural philosophy from the straitjacket of Aristotelianism, his non-polemical commentaries on Aristotle as well as his theological treatises have recently become more widely studied, translated, and appreciated.
