The several sides of the astragal or huckle bone had their character expressed by numbers, and obtained separate names, which determined the value of the throw.[515] Thus, the side showing the Monas was called the Dog, the opposite side Chias, and the throw Chios. In cockall as in dice there are neither twos nor fives. The highest number, six, was called the Coan (συνορικὸς or ἑξίτης); the Dog or one was called the Chian or dog-chance; to which the old proverb alluded Κῶος πρὸς χῖον, six to one. To have the Dog turn up was to lose, hence, perhaps, the phrase, “going to the dogs,” that is, playing a losing game. The throw of eight was denominated Stesichoros, because the poet’s tomb at Himera consisted of a perfect octagon. Among the forty who succeeded to the thirty at Athens Euripides was one, and hence, if the throw of the astragals amounted to forty points, they bestowed upon it the name of Euripides. All animals in which the astragal is found have it in the hough or pastern of the hind legs. The τὸ πρανὲς, the gibbous side or blank, because it counts for nothing; the τὸ κοῖλον, the hollow side or “put in;” the χῶα, the tortuous side, "cockall," or “take all,” so called because it wins the stake; the smooth side τα χῖα, “take half,” because of the money put in, it wins half. Among the Greeks and Romans the _put in_ was called trias, the blank tetras, the half-monas, and the cockall hexas.[516] By the Arabs they are denominated the thief, the lamb, the wezeer, and the sultan; by the Turks the robber, the ploughman, the kihaya, or the dog, and the bey; by the Persians the robber, the rustic, the wezeer, and the schah; by the Armenians the thief, the ploughman, the steward, and the lord. The number of casts among the Greeks, according to Eustathius, amounted to thirty-five.[517] Pliny[518] speaks of a work of Polycletos representing naked boys playing at this game, and the reader will probably remember the mutilated group in the British Museum, in which a boy having evidently been beaten at astragals, is biting in revenge the leg of his conqueror.
