Dionysius the Areopagite
The emperor Julian the Apostate was deeply influenced by neoplatonism, as was Hypatia of Alexandria. Neoplatonism influenced many Christians as well, including Pseudo-Dionysius the Areopagite. St. Augustine, though often referred to as a "Platonist," acquired his Platonist philosophy through the mediation of the Neoplatonist teachings of Plotinus.
