The ancient Irish tree alphabet was used exclusively by the druids, for the marking of graves and monuments, but also for oracles by the branch of druids known as the filid, or oracular poets whose task was to be the memory keepers, the guardians of ancestral and traditional lore. Ogham for them was a symbolic and magical system which used the example, image and metaphor of the trees, and their energies to signify and open up whole vistas of meaning accessible only to a magically elite and learned few.Although each ogham letter corresponds to a tree, and in the 20th century was given the added correspondences of months in a tree calendar by Robert Graves, their meaning is not limited to the tree they represent, but can be unlocked over time by meditation on the tree and associated quatrains and kennings contained in the few surviving texts that provide the sum of knowledge on the ogham, especially the 7th century ‘Scholars Primer’.However, these symbols have a power of their own, as well as their unique spiritual energies, which can be invoked for simple divination or magical purposes.They are divided into five aicmi (tribes). Sometimes a further five, the forfeda are included but they are a much later addition to accommodate consonants not included in the Irish alphabet.

Finns window, an oracular ‘map’ most probably used as a design upon which ogham sticks were cast for divination, was discovered in the 14th Century Book of Ballymote and like the ogham can also be used as a magical symbol in its own right as well as a mandala for contemplation and meditation. Finns window is sometimes known as Finn or Fionns shield, and is ofcourse named after the Irish hero Finn who ate the salmon of knowledge and recieved divine wisdom and magic as well as heroic prowess.
