In the Canary Islands, shepherds used to move along the steep slopes of the volcanic territory with spectacular jumps, with the aid of a pointed shaft. One of these is called the half moon in which the shepherd makes a 180° turn into the void, to cross the crevasses. Becoming a very common game among the Canary Islands natives, the Guanches of Berber origin, the Spanish domination represented a serious threat to existance of the game which, however, survived.
