In ancient Ireland, mythology and folklore were part of the general knowledge about each tree. This book gathers together the myths, legends, and folklore associated with the native Irish trees. The folklore has two main themes: the tree as a marker of important places such as royal site or holy well, and the role of different trees as source of magical power in folk customs and superstitions. Many themes are common to different trees, such as fertility, magical power, and the tree as a link between this world and the spiritual. Along with beautiful watercolors illustrating the different kinds of trees, the book features an Ogham tree calendar based on the early Irish alphabet and the ancient Celts' lunar calendar that links the trees to the different months of that calendar.
