Etymology : 1590s, from Latin paean “hymn of deliverance,” from Greek paian “hymn, chant, hymn to Apollo,” from Paian, a name of the god of healing; originally the physician of the gods (in Homer), later merged with Apollo; literally “one who touches” (i.e. “one who heals by a touch”), from paio “to touch, strike.”
