St. Agatha is one of the most highly venerated of the virgin martyrs in the early Church. Although there is little that is known about her life, tradition holds that she was born in Sicily to a noble family, and martyred there during the time of Emperor Decius in the third century. St. Agatha is among the saints commemorated in the Roman Canon (Eucharistic Prayer I).

~ “May the Virgin Martyr Saint Agatha implore your compassion for us, O Lord, we pray, for she found favor with you by the courage of her martyrdom and the merit of her chastity.
Through our Lord Jesus Christ.”
~ from the Proper of Saints, Daily Roman Missal
