Generally speaking, the type of society contributes to determining conceptions of animals – an agricultural society will have other perspectives than a society of hunters and gatherers, an industrial society or a late modern society. Conceptions of animals in the Roman Empire...

Damnatio ad bestias In the Roman Empire, the sentencing of humans to the beasts – damnatio ad bestias – was a punishment for severe crimes and not open to pardon (Ville 1981: 235–40).1 It implied being killed by animals in the arena and was a most shameful way to die, a punishment normally not imposed on Roman citizens.
