The letter C in the Ogham alphabet is represented by the Hazel tree (Old Irish word: 'Coll')
The Hazel tree was considered sacred to the ancient Celts, it was known as a fairy tree. People considered it extremely unlucky to burn the wood of the hazel tree and its nuts were described as the 'Nuts of Wisdom'
W.B Yeats considered the Hazel tree to be the Irish form of the tree of Wisdom
