Our ancestors were keenly aware of the nature of our indigenous trees. Each species of tree carried its own individual energy and spirit. We can deduce a little of what our ancestors knew of this from Irish mythology. We can augment this by our own experience of trees. For this we need to use our intuition and imagination to listen to the spirit of trees. If you add a detailed observation of the form of the tree in the way that scientists do you are starting to practice Goethian Science.
The Ogham alphabet was developed in the 4th century. Trees were used as names for the letters. This is a further confirmation of the importance of trees to our ancestors.
You can learn more about Ogham trees by participating in our druidry courses as Kilkenny Druidry College. You can also have an introduction to some of the Ogham Trees on our Wand & Staff making workshop. (Click on Wand and Staff making for further information).
