Via Sacra
The Battle of the Lacus Curtius took place in the Forum area between Romulus and Tatius, king of the Sabines. The Romans had been forced to retreat uphill on the Via Sacra. However, at the Porta Mugonia, Romulus prayed to Jupiter and vowed him a temple if he stemmed the Sabine advance. The Romans regrouped and held their ground, staving off defeat.
