Celtic Trinity-Button, 22 x 22 mm, Antique brass plated
A triskelion or triskele (both from the Greek τρισκέλιον or τρισκελής, for "three-legged") is a symbol consisting of three interlocked spirals, or three bent human legs, or any similar symbol with three protrusions and a threefold rotational symmetry. A triskelion is the symbol of Brittany, as well as the Isle of Man and Sicily (where it is called trinacria. The Manx and Sicilian triskelia feature three running legs, bent at the knee and conjoined at the crotch area. The triskelion symbol appears in many early cultures, including on Mycenaean vessels, on coinage in Lycia, and on staters of Pamphylia (at Aspendos, 370–333 BC) and Pisidia. It appears as a heraldic emblem on warriors' shields depicted on Greek pottery. A symbol of four conjoined legs, a tetraskelion, is also known in Anatolia. Celtic influences in Anatolia, epitomized by the Gauls who invaded and settled Galatia, are especially noted by those who theorize a Celtic origin for the triskelion.
