In the four hundred and thirteenth year of the Christian Era, some three hundred miles above Alexandria, the young monk Philammon was sitting on the edge of a low range of inland cliffs, crested with drifting sand. Behind him the desert sandwaste stretched, lifeless, interminable, reflecting its lurid glare on the horizon of the cloudless vault of blue. At his feet the sand dripped and trickled, in yellow rivulets, from crack to crack and ledge to ledge, or whirled past him in tiny jets of yellow smoke, before the fitful summer airs. Here and there, upon the face of the cliffs which walled in the opposite side of the narrow glen below, were cavernous tombs, huge old quarries, with obelisks and half-cut pillars, standing as the workmen had left them centuries before; the sand was slipping down and piling up around them, their heads were frosted with the arid snow; everywhere was silence, desolation - the grave of a dead nation, in a dying land.
