Orc (a proper name) is one of the characters in the complex mythology of William Blake. Unlike the medieval sea beast, or Tolkien's humanoid monster, his Orc is a positive figure, the embodiment of creative passion and energy, and stands opposed to Urizen, the embodiment of reason. Orc is described by Blake as 'Lover of Wild Rebellion, and transgressor of God's Law'. He symbolizes the spirit of rebellion and freedom, which provoked the French Revolution and American War of Independence. Orc appears in four of Blake's books - America, Europe, The Book of Urizen and The Four Zoas.

Orc is the child of Los and Enitharmon
