BOSK

The bosk, without which the Wagon Peoples could not live, is an oxlike creature. It is a huge, shambling animal, with a thick, humped neck and long, shaggy hair. It has a (page 5) wide head and tiny red eyes, a temper to match that of a sleen, and two long, wicked horns that reach out from its head and suddenly curve forward to terminate in fearful points. Some of these horns, on the larger animals, measured from tip to tip, exceed the length of two spears.
 
Not only does the flesh of the bosk and the milk of its cows furnish the Wagon Peoples with food and drink, but its hides cover the domelike wagons in which they dwell; its tanned and sewn skins cover their bodies; the leather of its hump is used for their shields; its sinews forms their thread; its bones and horns are split and tooled into implements of a hundred sorts, from awls, punches and spoons to drinking flagons and weapon tips; its hoofs are used for glues; its oils are used to grease their bodies against the cold. Even the dung of the bosk finds its uses on the treeless prairies, being dried and used for fuel. The bosk is said to be the Mother of the Wagon Peoples, and they reverence it as such. The man who kills one foolishly is strangled in thongs or suffocated in the hide of the animal he slew; if, for any reason, the man should kill a bosk cow with unborn young he is staked out, alive, in the path of the herd, and the march of the Wagon Peoples takes its way over him.

The hundred, rather than eight, bosk- that drew his wagon had been unyoked; they were huge, red bosk; their horns had been polished and their coats glistened from the comb and oils; their golden nose rings were set with jewels; necklaces of precious stones hung from the polished horns.

Behind them another four haruspexes, one from each People, carried a large wooden cage, made of sticks lashed together, which contained perhaps a dozen white vulos, domesticated pigeons. Then the women climb to the top of the high sides on the wagons and watch the war lanterns in the distance, reading them as well as the men. Seeing if the wagons must move, and in what direction.When the bosk horns sound the women cover the fires and prepare the men's weapons, bringing forth arrows and bows, and lances. The quivas are always in the saddle sheaths. The bosk are hitched up and slaves, who might otherwise take advantage of the tumult, are chained.

The Bosk is a large, horned, shambling ruminant of the Gorean plains. It is herded below the Gorean equator by the Wagon Peoples, but there are Bosk herds on ranches in the north as well, and peasants often keep some of the animals. Raiders of Gor, page 26

“What lazy animals those sleen are,” said Imnak. “They are not even really hungry, but they are keeping us in mind. They should be out hunting snow bosk, or basking sea sleen, or burrowing and scratching inland for hibernating leems.” Beasts of Gor, page 334
