Gaius Atilius Regulus Serranus

Gaius Atilius Regulus Serranus (fl. 250s BC) was a Roman Republican consul who twice held the consulship in the middle of the 3rd century BC. His elder brother, father, and grandfather were all consuls.
Career.
Atilius was consul for the first time in 257 BC, with the patrician Gnaeus Cornelius Blasio, and prosecuted the First Punic War against the Carthaginians. He defeated the Carthaginian fleet off the Liparaean islands, though not without considerable loss. He then obtained possession of the islands of Lipara and Melite, which he laid waste with fire and sword. On his return to Rome, he received the honour of a naval triumph.
Atilius was consul a second time in 250, with his patrician colleague being Lucius Manlius Vulso. In this year, the Romans gained a brilliant victory at Panormus, under the proconsul Lucius Caecilius Metellus. Thinking that the time had now come to bring the war to a conclusion, they sent both consuls to Sicily with an army of four legions and two hundred ships. Regulus and his colleague undertook the siege of Lilybaeum, the most important Carthaginian possession in Sicily; but they were foiled in their attempts to carry the place by storm and, after losing a great number of men, were obliged to turn the siege into a blockade.
According to William Smith, this Atilius is the first Atilius who bears the surname Serranus, which afterwards became the name of a distinct family in the gens. Caius Atilius Serranus, who was a praetor in 218 BC and a failed candidate for the consulship in 216, was his son and the ancestor of all subsequent praetors and consuls from this family. One of his descendants, Sextus Atilius Serranus, became a consul in 136 BC with Lucius Furius Philus (wrongly called Publius by Smith).
