Who was Valentinus the Gnostic teacher?

Valentinus was an Egyptian theologian who lived from around 100 to 165 CE and became the most successful early Christian Gnostic teacher of his time. He founded a school in Rome and taught a complex cosmological system dividing humanity into three distinct types: spiritual, psychical, and material. Although his original writings survive only in scattered fragments preserved by his critics, his influential movement, Valentinianism, spread widely across the Roman Empire.
