Who Was St. Barbara?
Legend places Barbara in Nicomedia during Diocletian's persecution, daughter of wealthy Dioscorus. Baptized secretly, she marked a cross on a tower wall and added a third window to a bathhouse to honor the Trinity. Denounced by her father, she was tortured and beheaded about 306; he died immediately after by lightning in the legend.
Cult spread among Byzantine and Western soldiers. Removed from universal calendar 1969 but devotion continues; feast December 4.
Barbara spent her days gazing upon the hills and admiring all of God's creations. She often pondered about the "First Cause and Creator of so harmonious and splendid a world." She soon realized the idols her father and teachers worshiped were not of God's creation.
Barbara secretly became a Christian and dedicated her life to knowing the true God and making Him known to others. She offered herself completely to the Lord, choosing a life of consecrated virginity. As Barbara grew older, her father began presenting men to her for marriage, but she refused them all and warned her father that his persistence could forever damage their relationship.

The Tower, the Lightning, and a Father’s Sword
St. Barbara is remembered as Virgin martyr of Nicomedia patron of artillerymen and miners. Architectural details can catechize when words are forbidden.
Barbara's father locked her in a tower to preserve her beauty yet she became Christian through tutors. He built a bathhouse with two windows; she insisted on a third for Trinity faith. Her father beheaded her and was struck by lightning, a tale miners and artillery crews retold.
Barbara's third window confesses Trinity in concrete form. This is not a private hobby of specialists. It is why the calendar still names December 4.
On this feast the Church is not only telling a story; she is keeping a school. While Barbara was out exploring the world, her father had a private bath-house built for her. The original architectural plans were for two windows, but while her father was away, Barbara advised the workers to make a third window, creating a Trinity of light. Barbara's bathhouse became a place full of healing power and many miracles occurred there.

After Dioscorus returned, Barbara informed him she had become a Christian and would no longer worship his idols. Full of rage, her father grabbed his sword and went to strike her. Before he could do so, Barbara ran off. Her father chased after her, but was abruptly stopped when a hill blocked his way. The hill opened and hid Barbara within a crevice, protecting her from her father's wrath.
Barbara, along with another virtuous Christian woman named Juliana, were tortured and led naked throughout the city. After Barbara prayed, an angel came and covered the pair with a robe, and torches used to burn Barbara went out when they came near her. Finally, Barbara was condemned to death by beheading by her father on December 4th. As a punishment for their actions, Dioscorus and Martianus were both killed after being struck by lightning.
