Proclus, one of the last great thinkers of Neoplatonic philosophy and ancient Greek philosophical thought in general, was born in Constantinople on February 8, 412 AD. Coming from a wealthy family from Lycia, he studied at the best educational centers of his time, Alexandria, Constantinople, Athens. There, he came into contact with the Athenian Neoplatonic Academy, which captivated him definitively and of which he became the director after the death of his teacher, Syrianus.

He died in Athens on April 17, 485 AD, and was buried near Lycabettus. Living in a time of syncretistic chaos, he would synthesize into a unified and complex system the entire preceding Neoplatonic philosophical tradition, influenced by Pythagorean, Aristotelian, and Stoic elements. In his system, he would consolidate the one god, the intelligible and intellectual hypostases, magic, and various demonic beings, thus delivering it to the scholastic Middle Ages.

His work serves as a fundamental source for any scholar of Neoplatonic philosophy, but also of Plato himself, whose interpretations he often offers as original and extremely interesting.
