The principal building also, which is thought to have been a palace, was a temple; but of a different sort. The travellers above say, that it is called Istachar: and Hyde repeats it, and tells us, that it signifies e rupe sumptum, seu rupe constans saxeum palatium: and that it is derived from the Arabic word sachr, rupes, in the eighth [691]conjugation. I am sorry, that I am obliged to controvert this learned man's opinion, and to encounter him upon his own ground, about a point of oriental etymology. I am entirely a stranger to the Persic, and Arabic languages; yet I cannot acquiesce in his opinion. I do not think that the words e rupe sumptum, vel rupe constans saxeum palatium, are at any rate materials, out of which a proper name could be constructed. The place to be sure, whether a palace, or a temple, is built of stone taken from the quarry, or rock: but what temple or palace is not? Can we believe that they would give as a proper name to one place, what was in a manner common to all; and choose for a characteristic what was so general and indeterminate? It is not to be supposed. Every symbol, and representation relates to the worship of the country: and all history shews that such places were sacred, and set apart for the adoration of fire, and the Deity of that element, called Ista, and Esta.[692] Ista-char, or Esta-char is the place or temple of Ista or Esta; who was the Hestia, Ἑστια, of the Greeks, and Vesta of the Romans. That the term originally related to fire we have the authority of Petavius. [693]Hebraïcâ linguâ אש ignem significat, Aramæâ אשתא quâ voce ignem a Noëmo vocatum Berosus prodidit: atque inde fortassis Græci Ἑστιας originem deduxerunt. Herbert, therefore, with great propriety, supposes the building to have been the temple of [694]Anaia, or Anaïs; who was the same as Hanes, as well as Hestia. Procopius, speaking of the sacred fire of the Persians, says expressly, that it was the very same which in aftertimes the Romans worshipped, and called the fire of Hestia, or Vesta. [695]Τουτο εστι το πυρ, ὁπερ Ἑστιαν εκαλουντο, και εσεβοντο εν τοις ὑστεροις χρονοις Ρωμαιοι. This is farther proved from a well known verse in Ovid. [696]Nec tu aliud Vestam, quam vivam intellige flammam. Hyde renders the term after Kæmpfer, Ista: but it was more commonly expressed Esta, and Asta. The Deity was also styled Astachan, which as a masculine signified Sol Dominus, sive Vulcanus Rex. This we may infer from a province in Parthia, remarkable for eruptions of fire, which was called [697]Asta-cana, rendered by the Romans Astacene, the region of the God of fire. The island Delos was famous for the worship of the sun: and we learn from Callimachus, that there were traditions of subterraneous fires bursting forth in many parts of it. [698]Φυκος ἁπαν κατεφλεξας, επει περικαιεο πυρι.
