Ancient Greek and Roman writers said that Dido was the founder and first Queen of Carthage. Carthage was a city in the country now known as Tunisia. Dido lived in the 9th century BC (about 3000 years ago). Some parts of her life may be true. Other parts are myths. She is best known from the story about her in the "Aeneid" by the Roman poet Virgil. In some writings about her, she is called Alyssa or Elissa. She was also worshipped as a goddess in ancient Carthage.
