Clooties

Many of the sites, now associated with Christianity, can be traced back to a time when the influence of Celtic druids flourished throughout Ireland. One of the remnants of this era, the rag tree, can still be seen throughout Ireland, to this day.
Recently I visited St. Patrick's Chair and Well. St Patrick’s Chair and Well (also known as the Druids Chair and Well) lies within Altadeven Wood, not far from the Ulster Way footpath, in County Tyrone. The chair is a huge 2m high stone block, shaped like a throne. The well, which is said to never run dry, is set within another rock close by. It is a 25 cm bullaun, or depression filled with natural water. According to folklore, this water has the power to heal.
Between the chair and the well is a small tree. It is still common practice today for people to tie rags as votive offerings for ailments to this tree. Tradition dictates that the pieces of cloth are dipped in the water of the well and then tied to a branch on the rag tree while a prayer is said to the spirit of the well. As the rag disintegrates over time, the ailment is supposed to fade away also.
The rags, and other offerings tied to the tree, are known as clooties.

My clootie (curious trinket) is the green wool

This is one of the remarkable places in Ireland that bridges that dark mysterious otherworld of the Druids, to Christianity and the modern world.
