TESTŪDO

( χελώνη ), a tortoise, was the name given to several other objects.—(1) To the Lyra, because it was sometimes made of a tortoise-shell.—(2) To an arched or vaulted roof.—(3) To a military machine moving upon wheels and roofed over, used in besieging cities, under which the soldiers worked in undermining the walls or otherwise destroying them. It was usually covered with raw hides, or other materials which could not easily be set on fire. The battering-ram [ Aries ] was frequently placed under a testudo of this kind, which was then called Testudo Arietaria .—(4) The name of testudo was also applied to the covering made by a close body of soldiers who placed their shields over their heads to secure themselves against the darts of the enemy. The shields fitted so closely together as to present one unbroken surface without any interstices between them, and were also so firm that men could walk upon them, and even horses and chariots be driven over them. A testudo was formed ( testudinem facere ) either in battle to ward off the arrows and other mi iles of the enemy, or, which was more frequently the case, to form a protection to the soldiers when they advanced to the walls or gates of a town for the purpose of attacking them. Sometimes the shields were disposed in such a way as to make the testudo slope. The soldiers in the first line stood upright, those in the second stooped a little, and each line succe ively was a little lower than the preceding down to the last, where the soldiers rested on one knee. Such a disposition of the shields was called fastigata testudo , on account of their sloping like the roof of a building. The advantages of this plan were obvious: the stones and mi iles thrown upon the shields rolled off them like water from a roof; besides which, other soldiers frequently advanced upon them to attack the enemy upon the walls. The Romans were accustomed to form this kind of testudo, as an exercise, in the games of the circus. IMG:6459379820872971714_ill369.jpg: Testudo. (From the An to nine Column.)
