Still north he sailed, up to Strangford Lough, where, landing, he made his first convert, the chief Dichu, and founded his first church—Down Patrick—where many years later he returned to die. Here for a time he sojourned. Before he turned south there was an errand he had to do, to bring his message to the valley of the Braid, in Antrim, where he had been a captive, herding swine on the slopes of Slemish. But at last, in the spring of 433, he set his face to the very core and centre of his purpose—the evangelization of Ireland at the fountain head of pagan civilization and pagan power. For the success of Patrick’s mission lay in this. He addressed himself to the chiefs, he bearded the pagan in his strong places: he won those who carried others with them.
