When you leave the Island of Angamanain and sail about a thousand miles in a direction a little south of west, you come to the Island of SEILAN, which is in good sooth the best Island of its size in the world. You must know that it has a compass of 2400 miles, but in old times it was greater still, for it then had a circuit of about 3600 miles, as you find in the charts of the mariners of those seas. But the north wind there blows with such strength that it has caused the sea to submerge a large part of the Island; and that is the reason why it is not so big now as it used to be. For you must know that, on the side where the north wind strikes, the Island is very low and flat, insomuch that in approaching on board ship from the high seas you do not see the land till you are right upon it. Now I will tell you all about this Island.
