(Latin: all, every)
Motto of Washington, District of Columbia, U.S.A. Also written in Latin as: Justicia omnibus.
Motto of Centenary College of Louisiana, Shreveport, Louisiana, USA; and the State of Oklahoma, USA.
The phrase/motto is a shortened form of Virgil's statement in his Georgics: Labor omnia vicit improbus, "Never-ending work conquered all things."
It is said that Virgil was describing the harshness of life following the Golden Age, when the earth had yielded its fruits without labor. Jupiter then decided to change everything, making life hard so mankind would learn and become independent.
Virgil, in the Aeneid, gives us this way to acknowledge a fact of life: No one can reasonably be expected to become expert in all things.
Motto of Harrods's Department Store (of London).
