34 Having then left Bruchium, he entered the oasis through the trackless desert, and there abode for a year, more or less. But, inasmuch as his fame had travelled there also, he felt that he could not be hidden in the East, where he was known to many by report and by sight, and began to think of taking ship for some solitary island, so that having been exposed to public view by the land, he might at least find concealment in the sea. Just about that time Hadrian, his disciple, arrived from Palestine with information that Julian was slain and that a Christian emperor had commenced his reign; he ought therefore, it was said, to return to the relics of his monastery.
But he, when he heard this, solemnly refused to return; and hiring a camel crossed the desert waste and reached Paretonium, a city on the coast of Libya. There the ill-starred Hadrian wishing to return to Palestine and unwilling to part with the renown so long attaching to his master's name, heaped reproaches upon him, and at last having packed up the presents which he had brought him from the brethren, set out without the knowledge of Hilarion. As I shall have no further opportunity of referring to this man, I would only record, for the terror of those who despise their masters, that after a little while he was attacked by the king's-evil and turned to a mass of corruption.
