In Greek mythology, Horkos (/ˈhɔːrkɒs/; Ancient Greek: Ὅρκος [hór.kos], lit. 'Oath')[1] personifies the curse that is inflicted on any person who swears a false oath.[2] According to Hesiod, Horkos was the son of Eris (Strife). He is one of the divine enforcers of oaths, which were an important part of the ancient Greek system of justice.
