Hippias

Hippias of Elis, a Greek sophist from the mid-5th century BC, was a contemporary of Socrates and Protagoras. He was known for his extensive knowledge and claimed mastery in diverse fields such as poetry, grammar, history, politics, mathematics, music, painting, and sculpture. He even boasted of crafting his own attire and accessories, showcasing a practical skill alongside his intellectual pursuits. Plato's dialogues, particularly the *Hippias major* and *Hippias minor*, depict Hippias as vain and arrogant, often highlighting his superficial understanding and boastful nature. Despite Plato's criticisms, Hippias was a renowned figure who lectured and traveled throughout Greece, influencing the education of youths. He is credited with originating the concept of natural law, which he considered universal and immutable, a notion that later influenced Cynicism and Stoicism and formed a foundation for Roman law. Hippias also contributed to the field of mathematics, with a discovery sometimes referred to as the quadratrix of Hippias. His historical work, the *Olympionikō̂n Anagraphḗ*, established the first Olympic victor list, dating Coroebus's victory to 776 BC, which became a standard for chronologies. His oratorical skills were notable, with Philostratus mentioning several public speeches delivered at Olympia. However, none of his written works have survived, though mentions of his writings on grammar, music, and other subjects exist in ancient texts.
