Isle of Man National Symbol

The National Symbol is the Three Legs of Man, first officially used in the early fourteenth century on the Manx Sword of State. The legs, clad in armour and bearing spurs, run in a clockwise direction and bear the Latin motto 'Quocunque Jeceris Stabit' or 'Whichever way you throw it, it will stand' - a testament to islanders' independence and resilience. The Three Legs also appear on the Manx Coat of Arms, flanked by a Peregrine Falcon and a Raven.

The source of the legs emblem is subject to many theories including the legend of the Island God Manannan, who is said to have set fire to the Legs in a fit of rage and hurled them down the hill in a burning wheel. The Legs are also related to Sicily's emblem of three naked legs surrounding the head of Medusa, and the swastika, both of which can be traced back to pagan symbols representing the Sun.
