Pelops was famous for his chariot race with King Oenomaus of Pisatis.[18] The winners of the events were admired and immortalised in poems and statues.[19] The Games were held every four years, and this period, known as an Olympiad, was used by Greeks as one of their units of time measurement. The Games were part of a cycle known as the Panhellenic Games, which included the Pythian Games, the Nemean Games, and the Isthmian Games.[20]
