coursing
the pursuit of game by hounds hunting by sight and not by scent. In modern, organized coursing competitions, two greyhounds at a time pursue one hare. The dogs are judged on performance as well as on their success in catching the hare: points are awarded for outracing the other dog and catching up with the hare, for turning it at a right angle, for wrenching (turning it at less than a right angle), for tripping the hare, and for a kill. Coursing was fully described about AD 150 by the Greek philosopher and historian Arrian in his Cynegeticus (translated as Arrian on Hunting).
