In the Temple of Diana, at Ephesus, there was a stone partly fashioned into the conventional form of the Ephesian Diana. This, it was asserted, had fallen down from the heavens. The stone is mentioned in the Acts of the Apostles (xix. 35), where we read that the city of the Ephesians was “a worshipper of the great goddess Diana, and of the _image_ which fell down from Jupiter.” In this text the word “image” has been supplied by the translators, a more literal rendering being “that which fell down from the sky.” This clearly shows that the stone only faintly indicated the human form. Tacitus says of the stone sacred to the Astarte (or Aphrodite) of Paphos, that it was a symbol of the goddess, not a human effigy, since it was an obscurely formed cone.[148] In his life of Apollonius of Tyana, Philostratus, also, mentions this stone and tells us that when Apollonius visited Paphos, he admired there “the famous symbolic figure of Aphrodite.”[149] These “living stones” λιθοι εμψυχοι were often covered with ornaments and vestments, and it has been conjectured that these adornments were, in some cases, changed so as to accord with the garments appropriate to certain special festivals of the respective gods.[150] The colossal emerald of the temple of Melkarth at Tyre is designated in the fragments of Sanchoniathon as an αεροπετῆ ἀστέρα, or star fallen from heaven. It was said to have been raised up by Astarte, and this last myth is represented on the silver coins of Marium in Cyprus. Here the radiance and splendor of the object suggested a stellar or celestial origin, and we see the same tendency at work in the application of the name _ceraunia_ (thunder-stones) to certain brilliant gems by Pliny.[151] Virgil[152] seems to confound with thunder the detonation of a bolide, followed by a train of light, and he seems also to confound the bolide itself with a lightning flash, for he says that its fall diffused a sulphurous vapor far and wide. Seneca was more critical, for he regarded the fact of thunder sometimes accompanying the fall of a meteorite as merely a coincidence. Although, in the absence of exact and trustworthy contemporaneous accounts of the fall of these sacred stones, we cannot be absolutely certain that they were meteorites, the testimony in several cases is sufficient to render this almost certain, while in many other cases there is no reason to doubt the substantial accuracy of the tradition. The choice of some of the _bætyli_, however, was determined by their form alone, to which was ascribed a religious significance, not exactly compatible with our religious ideas of to-day, but quite easily understood when we remember that the divine creative energy was concretely represented in ancient times by many symbols offensive to our sense of propriety.
