Publius Curiatius Fistus Trigeminus was a Roman politician in the 5th century BC, consul in 453 BC and decemvir in 451 BC.
Family
He was named Publius Curiatius by Livy, but named Publius Horatius by Dionysius of Halicarnassus. Diodorus Siculus calls him only Trigeminus. He could have been part of the gens Horatii rather than the Curiatii, two gentes that had opposed each other during the Roman monarchy in the fight of the Horatii and the Curiatii.
If he was part of the gens Curiatii, he was the only member of the family to become consul.
Biography
Consulship
In 453 BC, he was consul with Sextus Quinctilius Varus. Rome was ravaged in that year by a famine and an epidemic, which killed animals as well as people. It is thought to have been typhus, with the epidemic continuing on for ten or more years. His colleague, Varus, and Furius Medullinus Fusus, the consul suffect who replaced him, both died of the disease that same year.
Decemvirate
In 451 BC, he was part of the First Decemvirate which wrote the ten first tables of the Law of the Twelve Tables.
