Legio XIII Gemina

Legio XIII Gemina

Legio tertia decima Gemina (Thirteenth Twin Legion) was one of the most prominent Roman legions. It was one of Julius Caesar's key units in Gaul and in the civil war, and was the legion with which he famously crossed the Rubicon on January 10, 49 BC. The legion appears to have still been in existence in the fifth century. Its symbol was the lion.
