M. D’Anville’s position of this Temple is about thirty miles farther to the Southward; that is, from the Mediterranean; but he does not quote his authorities. In his _Geographie Ancienne Abregee_, vol. iii. p. 42. he has the following passage: “Selon la Géographie actuelle, ce qu’on trouve sous le nom de _Sant-rieh_, paroit en tenir la place; & par la Nature du pays, qui ne laisse point distinguer d’autre objet, on n’est point embarrassé sur le choix.” Edrisi (_Geo. Nub._ p. 41.) places _Sant-rie_ ten days Eastward from Augela, and nine days from the Mediterranean; which carries Sant-rie farther from the sea-coast, than Strabo allows to the Temple; but accords with Ptolemy. Savary, vol. ii. Lett. VIII.) quotes Abulfeda, to shew that the _Oases_ were only three days journey West of the Nile; and Ptolemy places the largest of them, named EL WAH by the Arabs, under the parallel of 27°. I suspect Abulfeda is wrong; and that Ptolemy is nearer the truth, when he allows one hundred and twenty-three miles, (or one hundred and five corrected) for the distance of the Great Oasis from Ptolemais on the Nile, in the direction of West, something Southwardly. Then Edrisi allows only nine days between Sant-rie and El Wah; whereas the scite of the Temple of Jupiter Ammon, by the above authorities, should be, according to my apprehension, at least twelve days from EL WAH. But we are young in African Geography: and as I have said before, the _data_ furnished by Arrian, Strabo, and Pliny, may satisfy us. The description of the _Oasis_ (or Island in the midst of the sandy Desart) which contained the Temple, is pretty generally known: but for the sake of those who may not recollect the particulars, I have extracted the following account. Arrian says, that it is not more than forty stadia in extent; Diodorus fifty; say, six or seven miles. All accounts agree, that it has one or more fountains of water; and that it was planted with divers kinds of fruit trees: Arrian particularly notices the Palm and Olive. What appeared to be a very great natural curiosity, was, a fountain, which according to Arrian, (whose account is the least extravagant) varied in its temperature, in a greater degree than any other that has been heard of: that is, it was very warm, or hot, at midnight; very cold in the heat of the day. I presume these phenomena will not appear very extraordinary to those, who consider, that a deep-seated spring will preserve a mean degree of temperature at all seasons: so that, in effect, it was the atmosphere that underwent the change; and with it, the bodies of those who made the observations.
