Book XII

. In either event if the blow was well aimed, and delivered with sufficient force, the knight was thrown backward off his steed. It might happen that both knights were struck, and succeeded in keeping their seat, while their spears were shivered, then a second joust must be ridden. If either knight were thrown from his saddle, or his steed fell with him, then he was held to be vanquished, but if, as not unfrequently happened, the girth of the saddle broke, and the rider were thrown, _then_ the joust was held to be undecided, and, in the case of real warfare, the issue was fought out with swords on foot. Cf. the combat between Parzival and Klamidé, Book IV . pp. 119, 120. In
