While I flail against an avalanche of paper while watching the snow pile up outside, consider this page on medieval predators and predation.
The spiritual threat to the human soul was expressed in the lethal relationship between predator and prey – the devil and demonic beings appear as predatory wild animals hunting or threatening humans often represented by suitable prey animals, particularly sheep. This imagery was rooted in the Bible, where carnivores feature as both expressions of God's power.
And there is an interesting diagram too.
