Iamblichus, also known as Iamblichus Chalcidensis, or Iamblichus of Apamea (Ancient Greek: Ιάμβλιχος, probably from Syriac or Aramaic ya-mlku, "He is king", c. 245–c. 325), was a Syrian Neoplatonist philosopher who determined the direction taken by later Neoplatonic philosophy. He is perhaps best known for his compendium on Pythagorean philosophy. (wikipedia)
