When we consider the extraordinary magnificence of the temple of Balbec, we cannot but be greatly surprised at the silence of the Greek and Roman authors in respect to it. Mr. Wood, who has carefully examined all the ancient authors, has found no mention of it, except in a fragment of John of Antioch, surnamed Malala, who attributes the building of it to Antoninus Pius. His words are:--"Ælius Antoninus Pius[138] built a great temple at Heliopolis, near Libanus, in Phoenicia, which was one of the wonders of the world." Some Roman medals also have been found, upon the reverse of which is a representation something similar to those temples, with the inscription:--COLONIA HELIOPOLITANA JOVI OPTIMO MAXIMO HELIOPOLITANO. One circumstance, however, militates against the idea that Antoninus Pius was the builder of these temples; viz., that Julius Capitolinus says nothing about them, though he gives a list of that emperor's buildings, and speaks of others of much less consideration. It must, however, be remembered, that the work of Julius Capitolinus is known to be so extremely defective, that though Antoninus reigned one-and-twenty years, and transmitted to posterity the character of one of the best princes that ever ruled, yet the particulars, that merited such extraordinary praise, are utterly unknown. Gibbon thus remarks upon the different fortunes of Balbec and Emesa:--"Among the cities which are enumerated by Greek and oriental names in the geography and conquest of Syria, we may distinguish EMESA and HELIOPOLIS; the former as a metropolis of the plain; the latter as the metropolis of the valley. Under the last of the Cæsars they were strong and populous; the turrets glittered from afar; an ample space was covered with public and private buildings; and the citizens were illustrious by their spirit, or at least by their pride; by their riches, or at least by their luxury. In the days of paganism, both Emesa and Heliopolis were addicted to the worship of Baal, or the sun: but the decline of their superstition or splendour has been marked by a singular variety of fortune. Not a vestige remains of the temple of Emesa, which was equalled in poetic style to the summits of Mount Libanus; while the ruins of Balbec, invisible to the writers of antiquity, excite the curiosity and wonder of European travellers."
