Ancient Romans with disabilities were recorded in the personal, medical, and legal writing of the period. While some disabled people were sought as slaves, others with disabilities that are now recognized by modern medicine were not considered disabled. Some disabilities were deemed more acceptable than others; while some were viewed as honorable characteristics or traits that increased morality, others, especially congenital conditions, resulted in infanticide. Rendering someone disabled was also used as a punishment. Some mobility aids, such as early prosthetics, have been documented. Small, scattered medical references contain the only direct acknowledgments of disability.
