"The virgin and chaste Catherine the wise..."

St. Catherine the Great Martyr and All-Wise (source)

The virgin and chaste Catherine the wise, who through the power of Christ, truly was strengthened, and entered the stadium with rejoicing. And she deposed the tyrant through her steadfastness, along with the whole multitude of the enemy foes, and she ceaselessly chanted with joy and with a great voice: O my Christ, You are my glory, my Savior and my Deliverer; do You receive my spirit.

-Kathisma from the feast of St. Catherine the Great Martyr
