Gnaeus Cornelius Lentulus Batiatus (or, possibly, Vatia) was the Roman owner of a gladiatorial school in Capua (near Mount Vesuvius), in southern Italy. 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).
Identity and origins 
Shackleton Bailey noted that the name ('Batiatus'), as recorded by the ancient historians, could be a corrupted form of the cognomen 'Vatia'. 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.
