Major Arts Studied by the Tuatha Dé Danann from Lebor Gabála (LGE, Section VII):
Druidechta – Druidry
Fessa – knowledge
Fástini - prophecy
Amainsechtai – magic
Cerdaib Suithe Gentliuchta – arts of pagan cunning
These arts and skills are grouped as the major categories of Druidecht (druidry) and Diabal-dan (demonic arts) in poem LXII of Lebor Gabála. Keating calls these wizardry, Druid rites and Devilcraft in his History of Ireland.
The four teachers of the Tuatha Dé Danann are Morfesa, Esras, Uiscias and Semias. They are called wizards (druids) and poets (filid) in the text and are said to teach occult lore (fios) and secret knowledge (éolas). In Lebor Gabála (poem LXII) they are called Sages (sair-leasa) and Poets (filid).
There is much to learn from the little that has been presented here. I hope that those who are reading this discover that which is hidden within each person so that it can change the world.
