How Latin names are chosen

Rome gave a child its given name at the dies lustricus, a purification held on the eighth day for a girl and the ninth for a boy. The delay was deliberate: until the umbilical stump fell away the infant was not regarded as having a separate existence, and so had no claim on a name or a fate of its own. The ceremony washed the child, presented it at the lararium before the household gods, and ended in a family feast. The praenomen given that day was only the first of the tria nomina — praenomen, nomen, cognomen — the three-part structure that marks Roman naming out from almost everything around it.
