It is difficult to reconstruct a hierarchy of the Carthaginian gods. It was common for the pantheons of Phoenician cities to be headed by a divine couple, entitled Baal (lord) and "Baalat" ("lady"). At Carthage, this divine couple appears to have consisted of the god Baal Hammon and the goddess Tanit, who appear frequently in inscriptions from the tophet of Salammbô, with which they seem to have been especially associated. From the fifth century BCE, Tanit begins to be mentioned before Baal Hammon in inscriptions and bears the title "Face of Baal" ("pene Baal"), perhaps indicating that she was seen as mediating between the worshipper and Baal Hammon. An anthropomorphic symbol, composed of a circular "head", horizontal "arms", and a triangular "body," which is frequently found on Carthaginian stelae, is known by modern scholars as the sign of Tanit, but it is not clear whether the Carthaginians themselves associated it with Tanit. The connections of Baal Hammon and Tanit to the Phoenician pantheon are debated: Tanit may have a Libyan origin, but some scholars connect her to the Phoenician goddesses Anat, Astarte or Asherah; Baal Hammon is sometimes connected to Melqart or El. The gods Eshmun and Melqart also had their own temples in Carthage. The priests of other gods are known from epigraphic evidence, include Ashtart (Astarte), Reshef, Sakon, and Shamash.
