This city was situated in that part of Egypt which is called the Delta. It was named Heliopolis, city of the sun, from the circumstance of there being a temple dedicated to the sun there; and here, according to historians, originated the tale in respect to the phoenix.

At this place, Cambyses, king of Persia, committed a very great extravagance; for he burned its temple, demolished all the palaces, and destroyed most of the monuments of antiquity that were then in it. Some obelisks, however, escaped his fury, which are still to be seen; others were transported to Rome.

In this city[260] Sesostris built two obelisks of extreme hard stone, brought from the quarries of Syene, at the extremity of Egypt. They were each 120 cubits high; that is, 30 fathoms, or 180 feet. The emperor Augustus, having made Egypt a province of the Roman empire, caused these two obelisks to be transplanted to Rome, one of which was afterwards broken to pieces. He durst not venture upon a third, which was of monstrous size. It was made in the reign of Rameses; and it is said that 20,000 men were employed in the cutting of it. Constantius, more daring than Augustus, ordered it to be removed to Rome. Two of these obelisks are still to be seen; as well as another of 100 cubits, or 25 fathoms high, and 8 cubits, or 2 fathoms in diameter. Caius CÆsar had it taken from Egypt in a ship of so odd a form, that, according to Pliny, the like had never been seen.

At Heliopolis, there remains only a solitary sphinx and an obelisk, to mark the site of the city of the sun, where Moses, Herodotus, and Plato, are said to have been instructed in the learning of the Egyptians; whose learning and arts brought even Greece for a pupil, and whose empire, says Bossuet, in regard to Egypt in general, had a character distinct from any other.

"This kingdom (says Rollin) bestowed its noblest labours and finest arts on the improving of mankind; and Greece was so sensible of this, that its most illustrious men,—as Homer, Pythagoras, Plato, even its great legislators, Lycurgus and Solon, with many more,—travelled into Egypt to complete their studies, and draw from that fountain whatever was most rare and valuable in every kind of learning. God himself has given this kingdom a glorious testimony, when, praising Moses, he says of him, that 'he was learned in all the wisdom of the Egyptians.' Such was the desire for encouraging the growth of scientific pursuits, that the discoverers of any useful invention received rewards suitable to their skill and labour. They studied natural history, geometry, and astronomy, and what is worthy of remark, they were so far masters of the latter science, as to be aware of the period required for the earth's annual revolutions, and fixed the year at 365 days 6 hours—a period which remained unaltered till the very recent change of the style. They likewise studied and improved the science of physic, in which they attained a certain proficiency. The persevering ingenuity and industry of the Egyptians are attested by the remains of their great works of art, which could not well be surpassed in modern times; and although their working classes were doomed to engage in the occupations of their fathers, and no others, as is still the custom in India, society might thereby be hampered, but the practice of handicrafts would be certainly improved. The Egyptians were also the first people who were acquainted with the process of communicating information by means of writing, or engraving on stone and metal; and were, consequently, the first who formed books and collected libraries. These repositories of learning they guarded with scrupulous care, and the titles they bore, naturally inspired a desire to enter them. They were called the "Office for the Diseases of the Soul," and that very justly; because the soul was there cured of ignorance, which, it will be allowed, is the source of many of the maladies of our mental faculties[261]."
