defend their claims at the time and place indicated, which would show that the principals were not expected to appear personally.[584] Under the North German law it rested with the appellant to demand the duel either with or without champions. If the defendant were crippled, and was on that account obliged to appear by a hired champion, then the appellant could put forward another to meet him. A defendant, moreover, who had suffered a previous conviction for theft or rapine was always obliged to appear personally. When the duel was decreed by the court, and not demanded by the appellant, then the accused could decline it if he could prove that the prosecutor had hired a champion.[585] The practical spirit of the Italians led to the universal substitution of champions for the principals; they were selected by the magistrates and were paid by the state when the parties were too poor to bear the expense.[586] In all these provisions for the putting forward of substitutes in the duel there is something so repugnant to the fierce and self-relying spirit in which the wager of battle found its origin, and the use of a professional gladiator is so inconsistent with the pious reference to the judgment of God, which was the ostensible excuse for the duel, that some external reason is required to account for its introduction. This reason is doubtless to be found in the liberty allowed of challenging witnesses, to which allusion has already been made (p. 121). The prevalence of this throughout Western Europe readily enabled parties, unwilling themselves to encounter the risks of a mortal struggle, to put forward some truculent bravo who swore unscrupulously, and whose evidence would require him to be forced out of court at the sword’s point.
