A Celtic cross is a symbol that combines the cross with a ring surrounding the intersection. It is the characteristic symbol of Celtic Christianity, though the symbol has older, pre-Christian origins. Such crosses formed a major part of Celtic art. There are numerous representations of crosses combined with a circle, even before Christianity. These crosses are often called 'sun crosses'. In Ireland, it is said that the Celtic cross was introduced to the island by Saint Patrick during his time converting the pagan Irish. It is believed that he combined the symbol of Christianity, a cross, with the symbol of the sun, a circle, to create the Celtic cross.
