Oracles were most frequently situated in the vicinity of some natural phenomena; this at Siwa consisted of a sacred spring known as “Fons Solis,” the “Fountain of the Sun,” which by its strangeness contributed to the divine qualities of the temple. Very probably it was the “Ein el Hammam” which lies about a quarter of a mile south of the temple ruins and is to-day one of the largest and most beautiful springs in the oasis. Ancient writers describe its waters as being warm in the morning, cold at noon and boiling hot at midnight. Blind, black fish lived in the pool, according to the Arabic history, which was connected with the rites of the temple. The water to-day is a trifle warmer than most of the springs, and for that reason it is the favourite bathing-place of the inhabitants of Aghourmi. I have stood by the spring at midnight and tested its warmth, but it seemed in no way to differ from the other springs, except that it was a very little warmer. There are many contemporary descriptions of the actual temple, and antiquarians have from time to time disputed as to its original size and form. It appears to have consisted of a main building, or sanctuary, surrounded by triple walls which enclosed the dwelling-places of the king, priests and the guards, standing on a rocky eminence among the palm groves. A smaller temple stood a few hundred yards south of the acropolis. The rock on which the village of Aghourmi now stands was evidently the site of the original temple and fortress, and the ruins below the village, known as “Omm Beyda,” are those of the minor temple. The two temples were connected by an underground passage.
