Et facere et pati fortia Romanum est
Et facere et pati fortia Romanum est is a Latin phrase meaning "Acting and suffering bravely is the attribute of a Roman." Its comes from Livy's Ab Urbe condita 2, 12, 9.
Origin
According to legend, a certain Mucius Cordus attempted to kill an Etruscan king Lars Porsena, who was besieging Rome. When the Etruscans caught him, he said “Romanus sum civis” (I am a Roman citizen) and continued with Et facere et pati fortia Romanum est. To prove his point, he held his right hand without flinching in a fire that the king had ordered to torture him. Porsena was so impressed by this, that he gave up the besiegement of Rome.[1]
In this way Mucius Cordus became an example for a brave and audacious Roman burgess. He is assumed to have got his byname “Scaevola” (The “left-hand”) because of his act.
Cicero was later famously to use the phrase Civis Romanus sum in a different context.
