The oldest story about Dido was written by Timaeus. He was an ancient Greek historian who lived in the 3rd century BC. One hundred years later, a Roman historian, Pompeius Trogus, wrote about her. His story about her is now lost, but a later Roman historian, Justin, wrote a summary of Trogus' story. In the stories by Timaeus and Trogus, Dido was the daughter of the King of Tyre (a city in the country now known as Lebanon). She was married to Acerbas who was a priest of Hercules. When Dido's brother Pygmalion killed Acerbas, Dido ran away. She took some of her people with her. They went first to Cyprus, and then to the north coast of Africa in the place now known as Tunisia.
