Ancient Greek religion
Richard August Reitzenstein (2 April 1861, Breslau – 23 March 1931, Göttingen) was a German classical philologist and scholar of Ancient Greek religion, hermetism and Gnosticism. He is described by Kurt Rudolph as “one of the most stimulating Gnostic scholars.” With Wilhelm Bousset, he was one of the major figures of the "Religionsgeschichtliche Schule" (history of religions school).
