The primary weapon of practically all cataphract forces throughout history was the lance. Cataphract lances (known in Greek as a "Kontos" ("oar") or in Latin as a "Contus") appeared much like the Hellenistic armies' "sarissae" used by the famed Greek phalanxes as an anti-cavalry weapon. They were roughly four meters in length, with a capped point made of iron, bronze, or even animal bone and usually wielded with both hands. Most had a chain attached to the horse's neck and at the end by a fastening attached to the horse's hind leg, which supported the use of the lance by transferring the full momentum of a horse's gallop to the thrust of the charge. Though they lacked stirrups, the traditional Roman saddle had four horns with which to secure the rider; enabling a soldier to stay seated upon the full impact. During the Sassanid era, the Persian military developed ever more secure saddles to "fasten" the rider to the horse's body, much like the later knightly saddles of Medieval Europe. These saddles had a cantle at the back of the saddle and two guard clamps that curved across the top of the rider's thighs and fastened to the saddle, thereby enabling the rider to stay properly seated, especially during violent contact in battle.
