Saint Eulalia (Aulaire, Aulazia, Olalla, Eulària) (†303), co-patron saint of Barcelona, was a 13-year-old Roman Christian virgin who suffered martyrdom in Barcelona during the persecution of Christians in the reign of emperor Diocletian. For refusing to recant her Christianity, the Romans subjected her to thirteen tortures; including: putting her into a barrel with knives stuck into it and rolling it down a street, cutting off her breasts, crucifixion on an X-shaped cross, and finally, decapitation. Her feast day is commemorated on February 12 (August 22 in the Orthodox Church)
