In Greek mythology, Canis Major represented the dog Laelaps, a gift from Zeus to Europa; or sometimes the hound of Procris, Diana’s nymph; or the one given by Aurora to Cephalus. So famous for its speed that Zeus elevated it to the sky. It was also considered to represent one of Orion’s hunting dogs, pursuing Lepus the Hare or helping Orion fight Taurus the Bull, within tales of Homer and Hesiod.
