Gnaeus Cornelius Lentulus Batiatus (or, possibly, Vatia) was the Roman owner of a gladiatorial school in Capua. It was from this school that, in 73 BC, the Thracian slave Spartacus and about 70 to 78 followers escaped. The break-out led to the slave rebellion known as the Third Servile War (73–71 BC).
Shackleton Bailey noted that the name ('Batiatus'), as recorded by the ancient historians, could be a corrupted form of the cognomenVatia. Cornelius Lentulus Vatia would then have been either a Servilius Vatia by birth adopted into the Cornelii Lentuli or else a Cornelius Lentulus by birth adopted into the Servilii Vatiae.
