The Judgment of the Nations, circa 520 AD, Mosaic, Ravenna, Basilica of Sant'Apollinare Nuovo, Italy. Said to be an early depiction of Lucifer. The halo represents power and not divinity like in later medieval art. The depiction of Lucifer/Hell as we know today was developed in the middle ages and later. Before his revolt he was described as God’s ‘anointed cherub’. Cherubs were often portrayed as blue angels to signify knowledge, not as a chubby child (putto/Greco-Roman deity Cupid/Eros).
