As we have stated, the chapels consecrated to Isis were demolished in the year 48 B. C. After Caesar's death, the triumvirs decided in 43 B. C. to erect a temple in her honor out of the public funds, undoubtedly to gain the favor of the masses. This action would have implied official recognition, but the project appears never to have been executed. If Antony had succeeded at Actium, Isis and Serapis would have entered Rome in triumph, but they were vanquished with Cleopatra; and when Augustus had become the master of the empire, he professed a deep aversion for the gods of his former enemies. Moreover, he could not have suffered the intrusion of the Egyptian clergy into the Roman sacerdotal class, whose guardian, restorer and chief he was. In 28 B. C. an ordinance was issued forbidding the erecting of altars to the Alexandrian divinities inside the sacred enclosure of the _pomerium_, and seven years later Agrippa extended this prohibitive regulation to a radius of a thousand paces around the {83} city. Tiberius acted on the same principle and in 19 A. D. instituted the bloodiest persecution against the priests of Isis that they ever suffered, in consequence of a scandalous affair in which a matron, a noble and some priests of Isis were implicated. All these police measures, however, were strangely ineffectual. The Egyptian worship was excluded from Rome and her immediate neighborhood in theory if not in fact, but the rest of the world remained open to its propaganda.[27] With the beginning of the empire it slowly invaded the center and the north of Italy and spread into the provinces. Merchants, sailors, slaves, artisans, Egyptian men of letters, even the discharged soldiers of the three legions cantoned in the valley of the Nile contributed to its diffusion. It entered Africa by way of Carthage, and the Danubian countries through the great emporium of Aquileia. The new province of Gaul was invaded through the valley of the Rhone. At that period many Oriental emigrants went to seek their fortunes in these new countries. Intimate relations existed between the cities of Arles and Alexandria, and we know that a colony of Egyptian Greeks, established at Nimes by Augustus, took the gods of their native country thither.[28] At the beginning of our era there set in that great movement of conversion that soon established the worship of Isis and Serapis from the outskirts of the Sahara to the vallum of Britain, and from the mountains of Asturias to the mouths of the Danube.
