There are several different luck symbols that have long been associated with Irish culture, the primary ones being the shamrock, leprechaun, and pot of gold at the end of the rainbow. Many people who get luck of the Irish tattoos are doing so in hope that they will bring themselves good fortune, usually not by the tattoo itself but with the good vibes that the tattoo brings their wearer. It's often that these good luck symbols will be accompanied by Irish Gaelic phrases and blessings, or even quotes from the Gaelic translated Bible. With regard to the history of good luck symbols in Ireland, the shamrock is thought to have been a pagan and druid good luck charm even before St. Patrick made it famous through his sermons and analogies comparing it to the Christian holy trinity. With regard to leprechauns and their associated symbols, historians have concluded that they were a part of Irish pagan mythology and were the bringers of great wealth.
