In the mythology of William Blake, Albion is the primeval man whose fall and division results in the Four Zoas: Urizen, Tharmas, Luvah/Orc and Urthona/Los.
In the mythical story of the founding of Britain, Albion was a giant and a son of Poseidon, the Greek god of the sea.
[1] The division of the primordial man is found in many mythic and mystic systems throughout the world, including Adam Kadmon in Kabbalah and Prajapati in the Rigveda.
Blake also uses the name Albion in its traditional meaning, as an ancient synonym for Britain, in his poem "A Little Boy Lost" in Songs of Experience.
