Step-by-step explanation:
Publius, derived from the same root as populus and publicus that mean "the people" or "of the people", was a Latin personal name (known as praenomen) chosen by the parents of a Roman child, after the eighth day of birth in the case of a girl, or after the ninth day in the case of a boy.
Along with Lucius, Gaius, and Marcus, Publius was a very common name used by both patrician and plebeian families throughout Roman history.
