Iamblichus (ca. 250 - ca. 330 AD). De vita Pythagoræ & Protrepticæ orationes ad philosophiam [On the Pythagorean Way]. Heidelberg, 1598. [S.1. 7.]
Iamblichus was the chief representative of Syrian Neoplatonism, though his influence spread over much of the ancient world. In De vita Pythagoræ Iamblichus was interested not so much in the actual life of Pythagoras as in how to live according to the principles of his philosophy. Through this Iamblichus sought to introduce his audience to his own neoplatonic philosophy which sought unification of the human soul with God.
