Victorinus of Pettau was a third-century bishop and theologian who served the Christian community in Poetovio, located in modern-day Slovenia. Likely born in Greece, he became a significant early Latin exegete, being among the first to use the Latin language for biblical commentary. His theological writings were heavily influenced by Origen, though his millennialist views occasionally drew criticism. He is remembered as a martyr who died during the persecutions led by Emperor Diocletian around 303 or 304.
