[There are two saints of this name very celebrated in Spain, whereof one is of Merida, the other, the subject of this notice, of Barcelona. The former is commemorated on the 10th of December; the latter on Feb. 12th. The former is said to have been aged twelve or thirteen, the latter aged fourteen. There is also a striking similarity in their acts and their legends; and it seems that writers have often confounded the one with the other, that is, supposing there were two saints, virgins and martyrs of this name. But it seems not improbable, that the Eulalia of Barcelona and her namesake of Merida are the same. Such a mistake as the making one saint into two might easily arise, if a portion of the relics of Eulalia of Barcelona had been transferred to Merida. Martyrologists as generally name a saint as "of such a place" by the place where his or her relics are, as by the scene of the martyrdom. The Roman Martyrology says, on Feb. 12th, "At Barcelona, in Spain, S. Eulalia, V., who endured the little-horse, hooks, and flames, in the reign of Diocletian, the Emperor, and was finally fastened to a cross,[36] and received the crown of Martyrdom." Usuardus says much the same. The Martyrologies of Bede, Ado, and Notker enter into fuller details. The feast of S. Eulalia is observed with an octave according to ancient custom, sanctioned by a decree of the Congregation of Rites, Dec. 6th, 1608, at Barcelona, even when it falls in Lent. It is difficult to fix the date of the Acts, but it is certain that we have not got them in their original form, though there is no reason for doubting their substantial authority.]
