Bran the Blessed - Celtic God of Rejuvenation and Protection, Lord of Ravens. He died protecting modern-day England, but his severed head continued talking and giving advice for several months afterward. When it at last stopped, it was buried in the White Hill, where some say the Tower of London stands today. According to folklore, that is why ravens still guard the Tower of London.
Lucifer by Guillaume Geefs, 1848 - "The word Lucifer means 'Bearer of Light' and describes the function and effect of the acosmic power that brings the gifts of forbidden wisdom, enlightenment, intellect, imagination and gnosis. Lucifer is within the esoteric context the secret, invisible and black fire (The First Sun/Son of the Black Light) that burns to ashes and dissolves all illusions, and awakens and strengthens the inner Black Flame and opens the all-seeing eye of the Self."
