A description of the desert in Diolcos, where the anchorites live.
And so when we had come, while still beginners, from the monasteries of Palestine, to a city of Egypt called Diolcos, 871 and were contemplating a large number of monks bound by the discipline of the Cœnobium, and trained in that excellent system of monasteries, which is also the earliest, we were also eager to see with all wisdom of heart another system as well which is still better, viz.: that of the anchorites, as we were incited thereto by the praises of it by everybody. For these men, having first lived for a very long time in Cœnobia, and having diligently learnt all the rules of patience and discretion, and acquired the virtues of humility and renunciation, and having perfectly overcome all their faults, in order to engage in most fearful conflicts with devils, penetrate the deepest recesses of the desert. Finding then that men of this sort were living near the river Nile in a place which is surrounded on one side by the same river, on the other by the expanse of the sea, and forms an island, habitable by none but monks seeking such recesses, since the saltness of the soil and dryness of the sand make it unfit for any cultivation—to these men, I say, we eagerly hastened, and were beyond measure astonished at their labours which they endure in the contemplation of the virtues and their love of solitude. For they are hampered by such a scarcity even of water that the care and exactness with which they portion it out is such as no miser would bestow in preserving and hoarding the most precious kind of wine. For they carry it three miles or even further from the bed of the above-mentioned river, for all necessary purposes; and the distance, great as it is, with sandy mountains in between, is doubled by the very great difficulty of the task.
Diolcos is mentioned again in the Conferences XVIII. i. Sozomen (VI. xxix.) speaks of two celebrated monasteries near there presided over by Piamun and John.
