The Ancient Wisdoms,
Old Welsh Prose from 21 Lessons of Merlyn: a study of Druid Magic & Lore by Douglas Monro. The ancient wisdom refers to the wisdom of the Ancient Druids and bardic tradition in Wales. The mythology of the Welsh Druids is often associated with the name of Taliesin, Merlyn, or Merlin, the wizard-like figure that J.R.R. Tolkien uses as a model for characters like Gandolph the Grey in Lord of the Rings. The ‘Wizards’ or Druids were actually the poets, philosophers, scientists, seekers and all- round wise men of their time. They have associations with other ancient sects such as the Pythagoreans and both were famous for keeping no records of knowledge.

Everything they learned was committed to memory, much of it was encoded and passed on verbally in song or poetry to preserve the sanctity of the words.
The Pythagoreans believed that number was sacred, for the Druids, it was the letter.

Consequently, they developed an intricate relationship with the alphabet. Each letter would have a plethora of associations and when each of those meanings combined in the word, it had tremendous power.
