The penetrating power of the cataphract's lance was recognized as being fearful by Roman writers, described as being capable of transfixing two men at once, as well as inflicting deep and mortal wounds even on opposing cavalries' mounts, and were definitely more potent than the regular one-handed spear used by most other cavalries of the period. Accounts of later period Middle Eastern cavalrymen wielding them told of occasions when it was capable of bursting through two layers of chain mail. There are also reliefs in Iran at Firuzabad showing Persian kings doing battle in a fashion not dissimilar to later depictions of jousts and mounted combat from the Medieval era.
