Contemporary depictions however imply that they were not as completely armoured as earlier Roman and Sassanid types—horse armour is noticeably absent. Byzantine cataphracts of the 10th century were drawn from the ranks of the middle class landowners through the theme system, providing the Byzantine Empire with a motivated and professional force. An experimental type of cataphract was brought to the fore in the 10th and 11th centuries known as the "klibanaphoros", "bearer of klibanion"—named after the clibanarius and a throwback to the very heavily armoured cavalry of earlier days. However, the traditional view is that after the loss of prestige, men and material and the horse-rearing plains of Anatolia after they lost the decisive Battle of Manzikert to lighter Turk cavalry, they slowly dropped out of use.
