Built on a technicality
A woman named Elissa ran from Tyre with a few ships and whatever she could carry, after her own brother had her husband killed for his money. Later, people called her Dido. On the coast of North Africa, the local king offered her only as much land as one ox hide could cover. So she had the hide cut into a single long thread, thin as string, and used it to circle an entire hill. That hill was Byrsa, a Greek pun on the word for ox hide. Ancient writers found that joke funny for about a thousand years. While digging the foundations, the settlers found a horse's skull and read it as a sign: this city would be good at two things, war and getting rich. That is the legend. It is a great story. It is also, as far as anyone can prove, only a story, and it should be read that way.
