Saint Odilia (or Odile or Ottilia) is a Saint venerated in the Roman Catholic Church, although according to the current liturgical calendar, her feast day (18 July) is not officially commemorated. She is a patroness of good eyesight.
Legend has few details about her. She is said to have lived in the 4th century and to have been the daughter of a ruler ("king") in Britain. Together with a group of other young women ("virgins") that included St Ursula, she was travelling in Germany, according to one account because they were on a pilgrimage to Rome, another claims that they were looking for a place to settle and quietly practise their faith. However, "barbarians" (huns according to the legend about St Ursula) intercepted them at the gates of Cologne and martyred them.
In 1287 Odilia appeared to a brother of the Crosier Order in Paris; and in response to her request her relics were traced in Cologne and moved to their motherhouse at Huy in Belgium. Along the way to Huy various cures of blindness and other infirmities happened.
