Mettus is known for only two people in the early history of Rome (7th/6th cents. BC), for the Sabine Mettus Curtius [I 2], a contemporary of Romulus (Dion. Hal. Ant. 2,42,2; 46,3; Lib. de praenominibus 1), and for Mettus Fufetius, the dictator of Alba Longa at the time of Tullus Hostilius  (Varro in Non. 2,443 L., Verg. Aen. 8,642 etc.). The form

tt indicates a shortened form of the name.
