Tarutia gens
The gens Tarutia, also found as Tarrutia, was an obscure plebeian family at ancient Rome. Few members of this gens are mentioned in Roman history, of whom the best-known is probably Lucius Tarutius Firmanus, a noted mathematician and astrologer of the first century BC. Origin
The nomen Tarutius is of Etruscan origin. Branches and cognomina
Firmanus, the cognomen of the mathematician Lucius Tarutius, was derived from his original home of Firmum in Picenum. Members

 Lucius Tarutius Firmanus, a friend of both Varro and Cicero, was a mathematician and astrologer. Varro consulted him regarding the life of Romulus, and Firmanus cast the ancient king's horoscope. He concluded that Romulus was born September 23, in the second year of the second Olympiad, 771 BC, and that Rome was founded on April 9. Varro rejected the later date in favour of the traditional celebration of Rome's founding on the Palilia, April 21. Tarutia C. l.
