Tanit was a Phoenician lunar goddess, worshipped as the patron goddess at Carthage.
Tanit was worshiped in Punic contexts in the Western Mediterranean, from Malta to Gades into Hellenistic times. From the fifth century BCE onwards Tanit is associated with that of Baal Hammon. She is given the epithet pene baal ("face of Baal") and the title rabat, the female form of rab (chief) (Markoe 2000:130). In North Africa, where the inscriptions and material remains are more plentiful, she was, as well as a consort of Baal Hammon, a heavenly goddess of war, a virginal (not married) mother goddess and nurse, and, less specifically, a symbol of fertility, as are most female forms. Several of the major Greek goddesses were identified with Tanit by the syncretic interpretatio graeca, which recognized as Greek deities in foreign guise the gods of most of the surrounding non-Hellene cultures.
