After leaving this they entered on another sea, which seemed like a clear, thin cloud; and it was so transparent, and appeared so light, that they thought at first it would not bear up the weight of the curragh.
Looking down, they could see, beneath the clear water, a beautiful country, with many mansions surrounded by groves and woods. In one place was a single tree; and, standing on its branches, they saw an animal fierce and terrible to look upon.
Round about the tree was a great herd of oxen grazing, and a man stood near to guard them, armed with shield and spear and sword; but when he looked up and saw the animal on the tree, he turned anon and fled with the utmost speed. Then the monster stretched forth his neck, and, darting his head downward, plunged his fangs into the back of the largest ox of the whole herd, lifted him off the ground into the tree, and swallowed him down in the twinkling of an eye; whereupon the whole herd took to flight.
When Maildun and his people saw this, they were seized with great terror; for they feared they should not be able to cross the sea over the monster, on account of the extreme mist-like thinness of the water; but after much difficulty and danger they got across it safely.
CHAPTER XXIV.
AN ISLAND GUARDED BY A WALL OF WATER.
When they came to the next island, they observed with astonishment that the sea rose up over it on every side, steep and high, standing, as it were, like a wall all round it. When the people of the island saw the voyagers, they rushed hither and thither, shouting, "There they are, surely! There they come again for another spoil!"
Then Maildun's people saw great numbers of men and women, all shouting and driving vast herds of horses, cows, and sheep. A woman began to pelt the crew from below with large nuts; she flung them so that they alighted on the waves round the boat, where they remained floating; and the crew gathered great quantities of them and kept them for eating.
When they turned to go away, the shouting ceased: and they heard one man calling aloud, "Where are they now?" and another answering him, "They are gone away!"
