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 honored 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
neighboring provinces, where, in some places, she is called St. Eulalie,
in others St. Olaire, St. Olacie, St. Occille, St. Olaille, and St.
Aulazie. Sainte-Aulaire and Sainte-Aulaye are names of two ancient
French families taken from this saint. Her acts deserve no notice. See
Tillemont, t. 5, in his account from Prudentius, of St. 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 St. Jerom,
Ado, Usuard, &c.
