Sin (Mandaeism)
In Mandaeism, Sin or Sen is the name for a divine figure associated with the Moon, who are part of the entourage of Ruha in the World of Darkness.
In Mandaean astrology, Sin is associated with miscarriages and abnormal births. Other names for Sin include Agzʿil, Ṭaṭmʿil, Ṣaurʿil, and Sira. Sin's name is derived from the Akkadian language name Sīnu, a moon deity in ancient Mesopotamian religion.
Chapter 53 of the Mandaean Book of John is about Sin.
