At age 16 Patrick was torn by Irish raiders from the villa of his father, Calpurnius, a deacon and minor local official, and carried into slavery in Ireland. He spent six bleak years there as a herdsman, during which he turned with fervour to his faith. Upon dreaming that the ship in which he was to escape was ready, he fled his master and found passage to Britain. There he came near to starvation and suffered a second brief captivity before he was reunited with his family. Thereafter, he may have paid a short visit to the Continent.
Then came the dream.
Utterly confident in the Lord, he journeyed far and wide, baptizing and confirming with untiring zeal. In diplomatic fashion he brought gifts to a kinglet here and a lawgiver there but accepted none from any. On at least one occasion, he was cast into chains. On another, he addressed with lyrical pathos a last farewell to his converts who had been slain or kidnapped by the soldiers of Coroticus.
