The difference in their port and appearance may also be considered. "Nequaquam visu ac specie æstimantibus pares. Corpus alteri magnitudine eximium, versicolori veste, pictisque et auro cælatis refulgens armis; media in altero militaris statura, modicaque in armis habilibus magis quam decoris species." In size and appearance, there was no resemblance. The frame of the Gaul was enormous. He wore a vest whose color was changeable, and his refulgent arms were highly ornamented and studded with gold. The Roman was of middle military stature, and his simple weapons were calculated for service and not for show. Of Goliath we read--He had a helmet of brass upon his head, and he was armed with a coat of mail. * * * And he had greaves of brass upon his legs, and a target of brass between his shoulders, and the staff of his spear was like a weaver's beam; and David took his staff in his hand, and chose him five smooth stones out of the brook, and put them in a shepherd's bag which he had, even in a scrip, and his sling was in his hand. The General's consent is given to Titus Manlius, in these words--"Perge et nomen Romanum invictum, juvantibus diis, præsta." Go, and have a care, the gods assisting thee, that the Roman name remains unconquered. And Saul said unto David, Go, and the Lord be with thee. The Philistine and the Gaul were both speedily killed, and here the parallel ends; for David hewed off the Philistine's head. The Roman was more generous than the child of Israel--"Jacentis inde corpus, ab omni alia vexatione intactum, uno torque spoliavit; quem, respersum cruore, collo circumdedit suo." He despoiled the body of his fallen foe, in no otherwise insulted, of a chain, which, bloody, as it was, he placed around his own neck. I cannot turn from this gallant story, without remarking, that this Titus Manlius must have been a terrible wag: Livy says, that his young companions having prepared him for the duel--"armatum adornatumque adversus Gallum stolide lætum, et (quoniam id quoque memoria dignum antiquis visum est) linguam, etiam ab irrisu exscrentem, producunt"--they brought him forward, armed and prepared for his conflict with the Gaul, childishly delighted, and (since the ancients have thought it worth repeating) waggishly thrusting his tongue out of his mouth, in derision of his antagonist. Doubtless, the challenge of Charles V. by Francis I., in which affair, Charles, in the opinion of some folks, showed a little, if the cant phrase be allowable, of the white feather, gave an impetus to the practice of duelling. Doubtless, the _wager of battel_ supplied something of the form and ceremony, the use of seconds, and measuring the lists, the signal of onset, &c. of modern duels: but the principle was in the bosom of Adam, and the practice is of the highest antiquity.
