She was the daughter of Etichon, the Duke of Alsace. From her birth, Odilia faced significant challenges; she was born blind, which led to a tragic response from her father. Etichon was reportedly furious upon learning that his only child was both a girl and handicapped. In his anger, he ordered her death. However, her mother, Bethswinda, intervened and persuaded him to spare her life. Instead of being killed, Odilia was sent away to be raised by nuns.

The nuns provided a nurturing environment for Odilia, instilling in her a strong sense of faith and love. A pivotal moment in her life occurred when she turned twelve years old. During her baptism at a nearby monastery, it is said that she miraculously regained her sight through the blessing of Bishop Erhard of Regensburg. This event marked a significant turning point not only for Odilia but also for her relationship with her father.

After regaining her sight, Odilia returned home to reconnect with her family. However, tensions arose again when Etichon attempted to arrange a marriage for his daughter with a wealthy suitor. Despite this pressure from her father she expressed her desire to become a nun. . This led to further conflict between them until one day when Etichon discovered that she had been secretly providing food to the poor. This act of charity softened his heart towards her aspirations.

Recognizing his daughter’s commitment to helping others and living out her faith, Etichon eventually granted Odilia control over his castle so that she could establish a convent and provide care for the needy. He also built a monastery at the foot of the hill where their castle stood to assist those who were elderly or infirm.

Odilia’s legacy continued after her death around 720 AD. She became known as the patron saint of those suffering from eye problems and is venerated in both the Eastern Orthodox Church and Roman Catholic Church.
