Archer is Chiron, a centaur, half man and half horse, who was known as a great sage among his kind in Greek mythology. He is the son of the Titan Cronus, patron of the harvest and the earth, and the deity Philyra, making him a Divine Spirit that would not normally qualify for the status of Heroic Spirit.
