Verified · JSTOR Daily — On This Day: The Founding of Rome

By Roman reckoning, the city was born on April 21, 753 BC, when Romulus plowed a sacred furrow around the Palatine Hill to mark its first boundary. The legend has him and his twin Remus, raised by a she-wolf, quarreling over the new settlement until Romulus killed his brother and gave the city his name.

The precise date was not handed down from the founders. It was calculated centuries later by the scholar Marcus Terentius Varro in the first century BC, who worked backward through lists of kings and consuls to pin the event to a single day.

The choice was no accident. April 21 was already the Parilia, an ancient herders’ festival honoring Pales, goddess of flocks. Romans still mark the day as Natale di Roma, the city’s birthday, with reenactments and ceremonies near the Palatine.
