Formerly a lady of the night in the days before the Roman Empire, she became the mistress of HERCULES after he won her in game of dice.
To prevent gossip, he advised her to get married quick. So she rushed out into the street and bumped matrimonially into Tarutius, an Etruscan property developer.
Now Tarutius just happened to own some very tasty real estate and was not in the best of health. When he died, ACCA-LARENTIA found herself in possession of the entire future site of Rome. What an inheritance!
But by a strange twist of fate, she mysteriously disappeared — leaving the whole lot to the state of Rome itself. This proved very handy for future generations. Whenever some neighboring state protested at city boundaries or Roman occupation, senators could wave ACCA-LARENTIA’s Last Will And Testament in their faces and cry: "Gotcha!"
She is also Mother of the LARES, which presumably happened when those famous Roman boundaries were being sorted out. In gratitude for her services, she was given her own festival, Laurentalia or Larentinalia, on the 23rd of December. At least everyone agrees on the date.
