Nauigatio sancti Brendani abbatis[/B]]
St Brendan again armed himself with the sign of the Cross, and said to the brethren: Put on more sail, and ply your oars more briskly, that we may get away-from this island. Hearing this, the savage man, above mentioned, rushed clown to the shore, bearing in his hand a tongs with a burning mass of the slag, of great size and intense heat, which he flung at once after the servants of Christ; but it did them no hurt, for they were protected by the sign of the Cross. It passed them at a furlongs distance, and where it fell into the sea, it fumed up like II. heap of burning coals, and a great smoke arose as if from a fiery furnace. When they had passed on about a mile beyond the spot where this burning mass had fallen, all the dwellers on the island crowded down to the shore, bearing, each of them, a large mass of burning slag, which they flung, everyone in turn, after the servants of God; and then they returned to their forges, which they blew up into mighty flames, so that the whole island seemed one globe of fire, and the sea on every side boiled up and foamed, like a caldron set on a fire well supplied with fuel. All the day the brethren, even when they were no longer within view of the island, heard a loud wailing from the inhabitants thereof, and a noisome stench was perceptible at a great distance. Then St Brendan sought to animate the courage of the brethren, saying: Soldiers of Christ, be strong in faith unfeigned and in the armour of the Spirit, for we are now on the confines of hell; watch, therefore, and act manfully.
