Lucius (, ;
Greek: Λούκιος
Loukios,
Etruscan:
Luvcie) is a male
given name derived from
Lucius (abbreviated
L.), one of the small group of common
Latin forenames (
praenomina) found in the culture of ancient
Rome. Lucius derives from
latin word
Lux (gen.
lucis), meaning "
light" (<
PIE *leuk- "brightness", Latin verb
lucere "to shine"), and is a
cognate of name
Lucas. Another etymology proposed is a derivation from
Etruscan Lauchum (or
Lauchme) meaning "
king", which however was transferred into Latin as
Lucumo.
