Women of the Celts in Myth, Legend and Story
I just ran across this website of local legends from the Isle of Pabay, a small island off the Isle of Skye, Scotland. Because this is written from a more local, folklore perspective it contains some interesting information, including the old Gaelic spellings . . .

The Isle of Skye is where the Warrior Priestess Scatha hosted a training camp for Celtic warriors including the legendary Cu Chulainn; the photo reference shows the Coolin' Mountains in the background, which bare the name of the ancient Hero . . . Anam Cara, Bonnie

"Sgathaich (Scatha) was a formidable woman, a teacher of war-craft and a prophetess (Druid?) who foretells Cu Chulainn's future through divination. She was reputed to be the matron of self-defence and female independence as well as the guardian of young people who seek to know their full potential. Men came from further afield than Gaul to train with. her, and if they passed her rigorous tests they were more feared than any other fighting men."
