According to Christian tradition, Dymphna was born in Ireland in the 7th century. Dymphna’s father Damon, a petty king of Oriel, was a pagan, but her mother was a devout Christian.
When Dymphna was 14 years old, she consecrated herself to Christ and took a vow of chastity. Shortly thereafter, her mother died. Damon had loved his wife deeply, and in the aftermath of her death his mental health sharply deteriorated. Eventually the king’s counsellors pressed him to remarry. Damon agreed, but only on the condition that his bride would be as beautiful as his deceased wife. After searching fruitlessly, Damon began to desire his daughter because of her strong resemblance to her mother.
When Dymphna learned of her father’s intentions she swore to uphold her vows, and fled his court along with her confessor Father Gerebernus, two trusted servants and the king’s fool. Together they sailed towards the continent, eventually landing in what is present-day Belgium, where they took refuge in the town of Geel. (Wikipedia)
