First of all what is Ogham ?

Well the Ogham is known to be the Celtic Tree alphabet, but you can also use the sigils and the trees  for magical purposes and you can create you own Ogham staves for divination.

The Ogham has twenty letters, also called the Feda,  that are associated with a tree or plant. Later on, five more letters were added to the system, which is known as the Forfeda.

The letters are divided into four groups, the aicme (tribe, family) of five letters each. 

When you start to research about the Ogham you will come across a few difficulties, for example it is not always really clear which trees or plants are meant. 

However I won't go into the history of Ogham, there are great books and also some online resources where you can do your own research, if you choose to do so.

My priorities for the blog posts here, and also for my videos, will be the lore and legends about each tree, the magical use of the Ogham and also how to use it as a divination system. 

Over the next months, I want to discover with you each tree, I want to write, and talk, about the Celtic lore, the magical uses of the trees, how you can work with its essence and of course also about the divination system. 


Above you can find an introduction video, where I also explain how you can make your own staves and how you can make contact with the trees.





The next video I show you below, is a guided meditation to connect with your tree spirit ally

Here is a very brief introduction of the Feda, but of course there will be much more information provided when I talk about each tree.  Click on the tree to get more information. 

I will add the Forfeda at a later point.

The Forfeda



Erynn Rowan Laurie describes the Forfeda as following:

 "Some ogam students find that using the forfeda enriches their experience with the ogam. Many of them would never dream of doing an ogam reading without them. Others find them problematic at best. These additional letters are not found in any of the stone inscriptions, and were only rarely used in the manuscripts. While they were added one at a time at a much later date than the original ogam letters were developed, they were certainly a part of the medieval ogam tradition and are a legitimate part of the system. "


I think she puts that beautifully and I will leave you with this quote for now before we will explore the Forfeda on a deeper level.
