What if the greatest horror of transformation isn't becoming something else, but remembering who you were?
In Greek mythology, Circe transformed Odysseus' men into swine. But Homer tells us that their minds remained human. They remembered who they were, and they knew what had happened to them.
Centuries and cultures away, Irish mythology tells a darker story. Sadhbh was a young woman who was transformed into a deer by the druid Fer Doirich. Her fate would bring her into the world of Fionn mac Cumhaill and the Fianna, where, for a brief time, she would find love, family and a life she thought she had lost forever.
But some stories of transformation do not have happy endings.
This is the story of Sadhbh, Fionn and Oisín, from the Fenian Cycle of Irish mythology. A story of love, loss, transformation and memory.
And perhaps, beneath it all, there is a question that belongs not only to Irish mythology, but to all of us: If you could forget your greatest sorrow, would you?
