The triskeles proper, composed of three human legs, is younger than the triple spiral found in decorations on Greek pottery — especially as a design shown on Hoplite shields and later Greek and Anatolian coinage. An early example is found on the Shield of Achilles in an Attic hydria of the late 6th century BCE. It is found on coinage in Lycia and on staters of Pamphylia (at Aspendos in 370–333 BCE) and Pisidia. The meaning of the Greek triskeles is not recorded directly. The Duc de Luynes, in his 1835 study, noted the co-occurrence of the symbol with the eagle, the cockerel, the head of Medusa, Perseus, three crescent moons, three ears of corn, and three grains of corn. From this, he reconstructed a feminine divine triad that he identified with the triple goddess Hecate.
