This study discusses the exclusion of women, slaves, and physically disabled individuals from the ancient Olympics, focusing on Goffman's theory of stigma. It also delves into how kalokagathia influenced beauty, athleticism, and virtue, reinforced hierarchies and stigmatized those who did not fit the idealized image. Overall, the study provides a comprehensive exploration of how ancient Greek ideals and societal structures stigmatized certain groups based on gender, social status, and physical ability. Femininity, slavery, and physical disability were the conspicuous stigmatized identities of ancient Greek societies. In ancient Greece, the concept of kalokagathia, intertwining physical beauty with moral and intellectual excellence, formed the basis of societal standards. This ideal, however, was exclusive, applying only to free men of good heritage, while women, slaves, and the physically disabled faced stigmatization based on physiognomic reasoning and body temperature distinctions. The stigma was based on physical deviations from the able-bodied male standard. The physiognomic concept hidden behind the ideal of kalokagathia reproduced the stigma. Body temperature played a significant role in shaping discriminatory practices, associating warmth with virtues and deeming the male body superior. Women were considered inferior due to their colder bodies, and slaves were viewed as cold and incapable, reinforcing social hierarchies. Women and slaves were excluded from athletic ideals because of their non-normative body temperatures, while the physically disabled were excluded due to their ugly/deformed bodies. The ancient Olympics showcased able-bodied men displaying their athletic arete. Women's visibility in the ancient Greek Olympics was only representative. Restricted from participating in public athletic events, women were also subject to strict prohibitions on competition in the ancient Olympic Games. Only in the chariot races were exceptions made for unmarried women. While Kyniska emerged as the first female Olympic champion in 396 BCE, opportunities for representative participation in the Olympic Games were limited to women of wealth and status. Sport in ancient Greece served as a means of distinguishing between free citizens and slaves. Slaves, the anonymous figures of the ancient Olympics, could only participate in horse and chariot races on behalf of their owners. Although some local festivals allowed slave participation in athletic activities, major events like the Olympic Games prohibited direct competition for slaves, emphasizing their exclusion. This stigma-based athletic exclusion made it impossible for slaves to represent themselves as competitors in the ancient Olympics. The physically disabled, on the other hand, were completely deprived of the opportunity to compete in the ancient Olympics; they could compete neither representatively nor anonymously. Discriminatory practices against the physically disabled, embedded in social structures reinforced by philosophical ideals, myths, religious stereotypes and sacrificial rituals, resulted in them remaining completely absent from the ancient Olympics.
