Barbara lived in the 4th century and brought up as a heathen. A tyrannical father, Dioscorus, had kept her jealously secluded in a lonely tower which he had built for that purpose. Here, in her forced solitude, she gave herself to prayer and study, and contrived to receive instruction and Baptism in secret by a Christian priest.
Barbara resisted her father's wish that she marry. Then on one occasion, during her father's absence, Barbara had three windows inserted into a bathhouse her father was constructing. Her purpose was thereby to honor the Trinity.
Dioscorus was enraged by her action and by her conversion. So he himself denounced her before the civil tribunal. She was horribly tortured, and at last was beheaded. Her own father, merciless to the last, acted as her executioner. God, however, speedily punished her persecutors. While her soul was being borne by angels to Paradise, a flash of lightning struck Dioscorus, and he was hurried before the judgment seat of God.
