De mysteriis

Iamblichus ( eye-AM-blik-əs; Ancient Greek: Ἰάμβλιχος, romanized: Iámblichos; Aramaic: 𐡉𐡌𐡋𐡊𐡅, romanized: Yamlīkū; c. 245 – c. 325) was a Syrian Arab Neoplatonic philosopher who determined a direction later taken by Neoplatonism. Iamblichus was also the biographer of the Greek mystic, philosopher, and mathematician Pythagoras. In addition to his philosophical contributions, his Protrepticus is important for the study of the sophists because it preserved about ten pages of an otherwise unknown sophist known as the Anonymus Iamblichi.
