The largest of the temples of Thebes, and of any in Egypt, is that of Carnac, on the site of the ancient Diospolis. Diodorus describes it as thirteen stadia, or about a mile and a half in circumference, which nearly agrees with the admeasurements of Denon. It has twelve principal entrances; and the body of the temple, which is preceded by a large court, consists of a prodigious hall or portico, the roof of which is supported by one hundred and thirty-four columns, some twenty-six, and others thirty feet in circumference; four beautiful obelisks then mark the entrance to the shrine, which consists of three apartments, built entirely of granite.
