Man may propose, but even an apostle cannot dispose of his fate as he will, or foretell under ordinary circumstances how the course of events will affect him. St. Paul intended to stay at Ephesus till Pentecost, which that year happened on May 28th. Circumstances however hastened his departure. We have been considering the story of St. Paul's residence in Ephesus, but hitherto we have not heard one word about the great Ephesian deity, Diana, as the Romans called her, or Artemis, as St. Luke, according to the ordinary local use, correctly calls her in the Greek text of the Acts, or Anaïtis, as her ancient name had been from early times at Ephesus and throughout Asia Minor.[195] If this riot had not happened, if our attention had not been thus called to Diana and her worship, there might have been a total blank in St. Luke's narrative concerning this famous deity, and her equally famous temple, which was at the time one of the wonders of the world. And then some scoffers reading in ancient history concerning the wonders of this temple, and finding the records of modern discoveries confirming the statements of antiquity might have triumphantly pointed to St. Luke's silence about Diana and the Ephesian temple as a proof of his ignorance. A mere passing riot alone has saved us from this difficulty. Now this case well illustrates the danger of arguing from silence. Silence concerning any special point is sometimes used as a proof that a particular writer knew nothing about it. But this is not the sound conclusion. Silence proves in itself nothing more than that the person who is silent either had no occasion to speak upon that point or else thought it wiser or more expedient to hold his tongue. Josephus, for instance, is silent about Christianity; but that is no proof that Christianity did not exist in his time, or that he knew nothing about it. His silence may simply have arisen because he found Christianity an awkward fact, and not knowing how to deal with it he left it alone. It is well to bear this simple law of historical evidence in mind, for a great many of the popular objections to the sacred narratives, both of the Old and New Testaments, are based upon the very dangerous ground of silence alone.[196] Let us, however, return to Diana of the Ephesians. The worship of the goddess Artemis dominated the whole city of Ephesus,[197] and helped to shape the destinies of St. Paul at this season, for while intending to stay at Ephesus till Pentecost at the end of May, the annual celebration of Artemisia, the feast of the patron deity of the city, happened, of which celebration Demetrius took advantage to raise a disturbance which hastened St. Paul's departure into Macedonia. [195] The student may consult on the identification of Artemis and the Oriental or Persian deity Anaïtis, the _Revue Archéologique_ for 1885, vol. ii., pp. 105-115, and Derenbourg and Saglio's _Dict. des Antiq._, s.v. Diana.
