Trees mirror in many ways the life cycle of human beings: they are born from seed, they breathe and drink, they grow to maturity, reproduce and eventually die from age or disease. Their branches, roots and the veins of their leaves resemble human blood vessels, and certain species even ooze a reddish, blood-like sap when damaged.

From ancient times, people appreciated the spiritual value of trees, singling out individual trees for special veneration. In Ireland the roots of tree worship reach deep into pagan Celtic religion and spirituality.

Christine Zucchelli looks at all the trees, from Fairy Thorns to Rag Trees, from Mass Bushes to Monument Trees.
