This holy virgin was brought up in the faith, and in the practice of piety, at Barcelona in Spain. In the persecution of Dioclesian under the cruel governor Dacian, she suffered the rack, and being at last crucified on it, joined the crown of martyrdom with that of virginity. Her relics are preserved at Barcelona, by which city she is honoured as its special patroness. She is titular saint of many churches, and her name is given to several villages of Guienne and Languedoc, and other neighbouring provinces, where, in some places, she is called Saint Eulalie, in others Saint Olaire, Saint Olacie, Saint Occille, Saint Olaille, and Saint Aulazie. Sainte-Aulaire and Sainte-Aulaye are names of two ancient French families taken from this saint. Her acts deserve no notice. See Tillemont in his account from Prudentius, of Saint Eulalia of Merida, with whom Vincent of Beauvais confounds her; but she is distinguished by the tradition of the Spanish churches, by the Mozarabic Missal, and by all the Martyrologies which bear the name of Saint Jerom, Ado, Usuard, etc.
