in demonology Naberius is the most valiant Marquis of Hell, and has nineteen legions of demons under his command. He makes men cunning in all arts (and sciences to most authors), but especially in Rhetoric, speaking with a hoarse voice. He also restores lost dignities and honours (although to Johann Weyer he procures the loss of them).

He is depicted as a crow or a black crane.

Concerning his name, it is unclear the association made with the Latin Cerberus.

Other spellings: Cerberus, Cerbere, Naberus.
