Firmus was a slave from Thrace who later fought in Spartacus' rebellion against the Roman Republic. Following the Battle at the Silarus River in 71 BC, he was crucified on the orders of Marcus Licinius Crassus.
Firmus was born in 110 BC, a member of the Asti tribe in southern Thrace, and was taken into slavery as a young adult during a brief fight with Roman legionaries. He was first bought by a wealthy Roman in Campania.
Firmus spent nearly two decades of his life as a Pastores, tending his masters field.
Firmus was experienced in battle against the Romans both in Thrace and during Spartacus' rebellion, skills that were put to good use through years as a Pastores defending his dominus' stock against thieves.
Firmus had a tall and muscled build, befitting that of a Pastores. He notably had dark hair and brown eyes, something not seen in a lot of Thracians.
