Throughout the whole length on each side are placed stone sphinxes, at the distance of 20 cubits or a little more from each other, so that there is one row of sphinxes on the right hand, and another on the left. Next after the sphinxes is a large propylon, then on proceeding further, another propylon, and then another. Neither the number of the propyla nor of the sphinxes is determined by any rule. They are different in different temples, as well as the length and breadth of the Dromi. [CAS. 805] Next to the propyla is the naos, which has a large and considerable pronaos; the sanctuary in proportion; there is no statue, at least not in human shape, but a representation of some of the brute animals. On each side of the pronaos project what are called the wings. These are two walls of equal height with the naos. At first the distance between them is a little more than the breadth of the foundation of the naos.[849] As you proceed onwards, the [base] lines incline towards one another till they approach within 50 or 60 cubits. These walls have large sculptured figures, very much like the Tyrrhenian (Etruscan) and very ancient works among the Greeks. There is also a building with a great number of pillars, as at Memphis, in the barbaric style; for, except the magnitude and number and rows of pillars, there is nothing pleasing nor easily described,[850] but rather a display of labour wasted. 29. At Heliopolis we saw large buildings in which the priests lived. For it is said that anciently this was the principal residence of the priests, who studied philosophy and astronomy. But there are no longer either such a body of persons or such pursuits. No one was pointed out to us on the spot, as presiding over these studies, but only persons who performed sacred rites, and who explained to strangers [the peculiarities of] the temples.
