(100-180 C.E.) Valentinus was born in Phrebonis in upper Egypt about 100 AD and educated in nearby Alexandria. There he became a disciple of the Christian teacher Theudas who had been a disciple of Saint Paul. He claimed that Theudas (See the Second "Apocalypse of James) taught him secret wisdom that Paul had taught privately to his inner circle. Some believe he was the writer or had a part in the writing of the Gnostic "Gospel of the Truth", "A Valentianian Exposition", and others. Also formed secular Gnostic groups who's written works are referred to as Valentinian. The " A Valentinian Exposition", explains in part the use of the "monad".
