Faustus.

About Faustus

Faustus is a Latin praenomen, or personal name. It was never particularly common at Rome, but may have been used more frequently in the countryside. The feminine form is Fausta. The name was not usually abbreviated, but is occasionally found abbreviated F. During the period of the Roman Empire, it was widely used as a cognomen, or surname. As the Roman nomenclature system began to break down towards the end of the Western Empire in the 4th and 5th centuries, Faustus once again became a personal name, and it has survived into modern times.
