Volsinius was born in Alesia in the Roman Province of Eastern Gaul to an Italian noble family. Volsinius was a catamite, a boy in a homosexual relationship with a man, and also liked to drink wine, making him an unsavoury figure. Gnaeus Volsinius became a General in the SPQR army and fought in campaigns against the Britons in France. In 224 BCE, he was one of the many generals stationed at Alesia when the Britons attacked the town. Gnaeus tried to break out but was slain, showing some valor in a life of strangeness.
