The Ogham Revelation
The Ogham Revelation (Celtic Wisdom) oracle cards by Peter Dean.
This deck includes 60 cards and a guidebook.
The Celts were afraid that the Romans, who occupied England and Wales, would invade Ireland also. So they created their own script so that they could send secret messages to each other.
It is called the Ohgam alphabet. But it's meaning goes much deeper.
Every letter also stands for a tree and has a spiritual divinatory interpretation.
