Legio XII Fulminata

Legio XII Fulminata ("Thunderbolt Twelfth Legion"), also known as Paterna, Victrix, Antiqua, Certa Constans, and Galliena, was a legion of the Imperial Roman army. It was originally levied by Julius Caesar in 58 BC, and the legion accompanied him during the Gallic Wars until 49 BC. The unit was still guarding the Euphrates River crossing near Melitene at the beginning of the 5th century.

The legion's emblem was a thunderbolt (on a shield fulmen).^[1] In later centuries it came to be called commonly, but incorrectly, the Legio Fulminatrix, the Thundering Legion.
