Ireland was converted to Christianity by Patrick in 431. Legend has it that he drove the snakes out of Ireland and defeated the Druids.
St Patrick’s Prayer
I arise today
Through the strength of haven,
Light of sun.
Radiance of moon,
Splendor of fire,
Speed of lightening,
Swiftness of wind,
Depth of sea,
Stability of earth,
Firmness of rock
Through the creator of creation.
