Juturna in the context of "Turnus"

Regillus was an ancient lake of Latium, Italy, famous in the legendary history of Rome as the lake near which the Battle of Lake Regillus took place in 496 B.C. between the Romans and the Latins which finally decided the hegemony of Rome in Latium. The lake, now drained, was near the present-day town of Frascati.

During the battle, so the story runs, the Roman dictator Postumius vowed to build a temple to the twin gods Castor and Pollux, who were specially venerated in Tusculum, the chief city of the Latins (it being a Roman custom to invoke the aid of the gods of the enemy). The pair duly appeared during the battle dressed in white armour riding white horses, helped the Romans to prevail, and afterwards took the news of the victory to Rome. There they watered their horses at the spring of Juturna, close to which their temple in the Forum was subsequently erected.

Fontus or Fons (pl.: Fontes, "Font" or "Source") was a god of wells and springs in ancient Roman religion. A religious festival called the Fontinalia was held on October 13 in his honor. Throughout the city, fountains and wellheads were adorned with garlands.

Fontus was the son of Juturna and Janus. Numa Pompilius, second king of Rome, was supposed to have been buried near the altar of Fontus (ara Fontis) on the Janiculum. William Warde Fowler observed that between 259 and 241 BC, cults were founded for Juturna, Fons, and the Tempestates, all having to do with sources of water. As a god of pure water, Fons can be placed in opposition to Liber as a god of wine identified with Bacchus.

Gaius Lutatius Catulus (fl. 242–241 BC) was a Roman statesman and naval commander in the First Punic War. He was born a member of the plebeian gens Lutatius. His cognomen "Catulus" means "puppy". There are no historical records of his life prior to consulship, but his career probably followed the standard cursus honorum, beginning with service in the cavalry and continuing with the positions of military tribune and quaestor.

He was elected as a consul in 242 BC, a novus homo. His colleague as consul was Aulus Postumius Albinus. In addition to the consulship Postumius held the position of Flamen Martialis, and for this reason the pontifex maximus Lucius Caecilius Metellus forbade him from leaving the city. Lutatius was therefore the only candidate for commanding the war in Sicily. The senate appointed the praetor Quintus Valerius Falto as his second-in-command. This was somewhat of a novelty, since a second praetorship was created only a few years earlier, thereby allowing one of the praetors to leave Rome. Typically the two consuls shared the command of the army.
