Pompeo m
Italian: from the old Roman family name Pompeius, of uncertain origin. It is probably derived from an Italic dialectal word for ‘five’, and so is ultimately a doublet of QUINTUS (SEE Quintus) and PONS (SEE Pons). The name was borne by a few early saints, but owes its modern use to revival during the Renaissance, in tribute to the Roman general and statesman Pompey the Great (Gnaeus Pompeius Magnus, 106–48 BC).
