Philoponus 
Philoponus: Against Proclus On the Eternity of the World 6-8 [PDF ebook] 

This is one of the most interesting of all post-Aristotelian Greek philosophical texts, written at a crucial moment in the defeat of paganism by Christianity, AD 529, when the Emperor Justinian closed the pagan Neoplatonist school in Athens. Philoponus in Alexandria was a brilliant Christian philosopher, steeped in Neoplatonism, who turned the pagans » ideas against them. Here he attacks the most devout of the earlier Athenian pagan philosophers, Proclus, defending the distinctively Christian view that the universe had a beginning against Proclus » eighteen arguments to the contrary, which are discussed in eighteen chapters. Chapters 6-8 are translated in this volume.
