Melqart (Phoenician: U0001090cU0001090bU0001090aU00010912U00010913U00010915, lit. Melek-qart, “King of the City”; Akkadian: Milqartu) was the tutelary god of the Phoenician city of Tyre. Melqart was often titled Ba‘l Ṣūr, “Lord of Tyre”, and considered to be the ancestor of the Tyrian royal family. In Greek, by interpretatio graeca he was identified with Heracles and referred to as the Tyrian Herakles.
