The beautiful prayer of St. Patrick, popularly known as “St. Patrick's Breast-Plate”, is supposed to have been composed by him in preparation for this victory over Paganism. (The following is a (partial) literal translation from the old Irish text:)
I bind to myself today
The power of Heaven,
The light of the sun,
The brightness of the moon,
The splendour of fire,
The flashing of lightning,
The swiftness of wind,
The depth of sea,
The stability of earth,
The compactness of rocks.
I bind to myself today
God's Power to guide me,
God's Might to uphold me,
God's Wisdom to teach me,
God's Eye to watch over me,
God's Ear to hear me,
God's Word to give me speech,
God's Hand to guide me,
God's Way to lie before me,
God's Shield to shelter me,
God's Host to secure me...
(Snip)
Christ with me, Christ before me,
Christ behind me, Christ within me,
Christ beneath me, Christ above me,
Christ at my right, Christ at my left,
Christ in the fort,
Christ in the chariot seat,
Christ in the poop [deck],
Christ in the heart of everyone who thinks of me,
Christ in the mouth of everyone who speaks to me,
Christ in every eye that sees me,
Christ in every ear that hears me.
