Leviathan - Envy

Leviathan, the third demon prince, stood in for the envious sin. This one might sound a little strange because most people associate the leviathan with a giant sea monster, not exactly what you'd expect to find in hell.

This relationship with envy and the princes of hell that Binsfield refers to is a Christian idea, though it has thousands of interpretations and connotations across many different religions.

It was referred to by the Catholic priest and Italian philosopher Thomas Aquinas as a demonic creature that sucked the envious person whole as a form of punishment. Leviathan was frequently associated with the gates of hell.

The Hellmouth, also known as the Jaws of Hell, was depicted as the gateway to hell in Anglo-Saxon art. It's possible that the creature's gaping mouth was enough to impact this Anglo-Saxon motif because the Leviathan was viewed as a variety of species, including a big sea serpent, a large whale, and even a crocodile.
