Another spurious Christian work of about the same time is the _Clementina_, or the _Recognitions of Clemens_, Bishop of Rome. It is an account of the travels of the Apostle Peter and his conversation with Simon Magus; but the author's knowledge of the Egyptian mythology, of the opinions of the Greek philosophers, and of the astrological rules by which fortunes are foretold from the planets' places, amply prove that he was an Egyptian or an Alexandrian. No name ranked higher among the Christians than that of Clemens Romanus; and this is only one out of several cases of Christian authors who wished to give weight to their own opinions by passing them upon the world as his writings. Marcus Aurelius, who died in 181 A.D., had pardoned the children of the rebel general Avidius Cassius, but Commodus began his reign by putting them to death; and, while thus disregarding the example and advice of his father, he paid his memory the idle compliment of continuing his series of dates on his own coins. But the Egyptian coinage of Commodus clearly betrays the sad change that was gradually taking place in the arts of the country; we no longer see the former beauty and variety of subjects; and the silver, which had before been very much mixed with copper, was under Commodus hardly to be known from brass. [Illustration: 125.jpg CARTOUCHE OF COMMODUS] Commodus was very partial to the Egyptian superstitions, and he adopted the tonsure, and had his head shaven like a priest of Isis, that he might more properly carry an Anubis staff in sacred processions, which continued to be a feature of the religious activities of the age. Upper Egypt had latterly been falling off in population. It had been drained of all its hoarded wealth. Its carrying trade through Koptos to the Red Sea was much lessened. Any tribute that its temples received from the piety of the neighbourhood was small. Nubia was a desert; and a few soldiers at Syene were enough to guard the poverty of the Thebaid from the inroads of the Blemmyes. It was no longer necessary to send criminals to the Oasis; it was enough to banish them to the neighbourhood of Thebes. Hence we learn but little of the state of the country. Now and then a traveller, after measuring the pyramids of Memphis and the underground tombs of Thebes, might venture as far as the cataracts, and watch the sun at noon on the longest day shining to the bottom of the sacred well at Syene, like the orator Aristides and his friend Dion. But such travellers were few; the majority of those who made this journey have left the fact on record.
