Menander (Greek: Μένανδρος) was a first-century AD Samaritan Gnostic and magician. He belonged to the school of the Simonians, becoming its leader after the death of his master and instructor, Simon Magus, who was in Rome during the reign of Emperor Claudius.[1][2][3]
He is mentioned in the works of Irenaeus, Tertullian and others.[4] Justin Martyr is the oldest source of knowledge about Menander after he met some of the devoted Menandrians in their old age.
