Caecilia gens
The gens Caecilia was a plebeian family at ancient Rome. Members of this gens are mentioned in history as early as the fifth century BC, but the first of the Caecilii who obtained the consulship was Lucius Caecilius Metellus Denter, in 284 BC. The Caecilii Metelli were one of the most powerful families of the late Republic, from the decades before the First Punic War down to the time of Augustus. Origin. Like other Roman families in the later times of the Republic, the Caecilii traced their origin to a mythical personage, Caeculus, the founder of Praeneste. He  was said to be the son of Vulcan, and engendered by a spark; a similar story was told of Servius Tullius. He was exposed as an infant, but preserved by his divine father, and raised by maidens. He grew up amongst the shepherds, and became a highwayman. Coming of age, he called upon the people of the countryside to build a new town, convincing them with the aid of a miracle. An alternative tradition claimed that the Caecilii were descended from Caecas, one of the companions of Aeneas, who came with him to Italy after the sack of Troy. Praenomina . The praenomina used by the Caecilii during the Republic are "Lucius", "Quintus", "Gaius", and "Marcus". "Titus" appears only towards the very end of the Republic, and is not known to have been used by the great house of the Caecilii Metelli. Branches and cognomina. The cognomina of this gens under the Republic are "Bassus", "Denter, Cornutus", "Metellus", "Niger", and "Rufus", of which the Metelli are the best known. From the consulship of Lucius Caecilius Metellus Denter, the family of the Metelli became one of the most distinguished at Rome. In the latter half of the second century BC, it obtained  an extraordinary number of the highest offices of the state. Quintus Metellus, who was consul in 143 BC, had four sons, who were raised to the consulship in succession; and his brother, Lucius Metellus, who was consul in 142, had two sons, who were likewise elevated to the same dignity. The Metelli were distinguished as a family for their unwavering support of the party of the Optimates. The etymology of their name is quite uncertain. Festus connects it, probably from mere similarity of sound, with . The history of the family is very difficult to trace, and in many parts conjectural . It is treated at length by Drumann. The victory of the consul L. Caecilius Metellus against Hasdrubal's elephants at Panormus in 251 seems to have left a durable impression on the Caecili Metelli, as many of them featured an elephant on the coins they minted. In fact, elephants are so often used on their coins that it might have become their emblem.
