Isle of Man Flag
The national flag of Man is a plain red field with the "trinacria" emblem in the centre. The emblem dates back to the 13th century and is believed to be connected with Sicily, where a similar device was used in the Norman period. This connection with Sicily probably comes about through the Norse occupation of the Isle of Man from about 979 to 1265. The Three Legs emblem appeared on the 10th century coinage of the Norse King Analaf Cuaran who ruled both in Dublin and in Mann.
The design actually has a long history stretching back into pagan times and represents the sun and its daily passage across the heavens.It has been found among Celts and Norsemen of north-western Europe.
