James O'Leary, The Most Ancient Lives of Saint Patrick… (1874)
“ And the saint blessed him, prophesying what the Lord had determined for him, saying; "Unto this land shalt thou succeed, and from thy loins shall kings proceed, and reign through many generations." And in that place did the saint by his prayers produce out of the heart of the earth a pure fountain, which to this day is called Slan, that is, healing; for that it relieveth many laboring under multiplied diseases. And for his perverseness Seranus was driven from that land; and according to the word of the saint, the kingdom was given to his younger brother, Colladius. ”
