When the Ethiopian left Egypt , the blind man (it is said) was king once more, returning from the marshes where he had lived for fifty years on an island that he built of ashes and earth; for the Egyptians who were to bring him food without the Ethiopian's knowledge were instructed by the king to bring ashes whenever they came, to add to their gift. This island was never discovered before the time of Amyrtaeus; all the kings before him sought it in vain for more than seven hundred years. The name of it is Elbo, and it is over a mile long and of an equal breadth.
