The celebrated _Carrocio_ or Car Standard of the Italians appears to have been invented during the war between the Milanese and the Emperor Conrad, about 1035, by Heribert, the archbishop of Milan. This car had four wheels, and was drawn by four yoke of oxen, caparisoned in red. The chariot itself was red: in the midst of it was a tall red mast, surmounted by a golden globe, and bearing the banner of the city: beneath the banner was a large crucifix, of which "the extended arms appeared to bless the troops." A kind of platform in front of the _carrocium_ was occupied by a company of chosen heroes, elected for its especial defence; while, on a similar platform behind, the trumpets of the army contributed by their inspiriting strains to give confidence to all around. Before leaving the city, mass was solemnised upon the platform of the chariot, and not unfrequently a chaplain was assigned to accompany it into the field of battle, and to give absolution to the wounded. This device of the Milanese was soon imitated by others of the Italian cities, and with all it was held to be in the last degree humiliating to abandon the _carrocio_ to the enemy[147]. Other origins have, however, been given to the Car Standard. It has been attributed to the Saracens; and the monk Egidius ascribes its invention to the Duke of Louvain, who caused the banner which had been embroidered by the Queen of England to be placed in a superb chariot drawn by four oxen. The Italians have a large balance of evidence on their side. Of the various kinds of "GYNS" in use, the notices are not very distinct. And a chief source of the vagueness arises from the circumstance that, as the earliest chroniclers wrote in Latin, they applied the names of Roman engines to instruments which probably differed both in form and principle from their ancient prototypes. Tacitus, indeed, tells us that the barbarians borrowed these engines from those of the Romans; deserters or prisoners from whose ranks taught to the Northmen the art of their construction. But there seems good reason to believe that the motive principle of the classic periers, _torsion_, was no longer in use among the middle-age engineers: their instruments consisting of a lever furnished at one extremity with a sling and at the other with a heavy weight; the sudden liberation of the latter contributing the force necessary to propel the stone from the sling. See this subject fully discussed in the second volume of the _Études sur l'Artillerie_ of the Emperor of the French; and compare the evidences furnished by monuments of the twelfth and thirteenth centuries, given in later pages of this work.
