First Hadrian made him lead him along the seashore by the Bruchiom to the temple of Poseidon, where he performed some devotions, then he looked into the garden of the palace and the courts of the adjoining museum. The Caesareum with its Egyptian gateway excited his admiration no less than the theatre, surrounded with pillared arcades in stories, and decorated with numerous statues. From thence deviating to the left they once more approached the sea to visit the great Emporium, to see the forest of masts of Eunostus, and the finely-constructed quays. They left the viaduct known as the Heptastadion to their right and the harbor of Kibotus, swarming with small merchant craft, did not detain them long. Here they turned backs on the sea following a street which led inland through the quarter called Khakotis inhabited only by native Egyptians, and here the Roman found much to see that was noteworthy. First he and his companions met a procession of the priests who serve the gods of the Nile valley, carrying reliquaries and sacred vessels, with images of the gods and sacred animals, and tending towards the Serapeum which towered high above the streets in the vicinity. Hadrian did not visit the temple, but he inspected the chariots which carried people along an inclined road which led up the hill on which was the sanctuary, and watched devotees on foot who mounted by an endless flight of steps constructed on purpose; these grew wider towards the top, terminating in a platform where four mighty pillars bore up a boldly-curved cupola. Nothing looked down upon the temple-building which with its halls, galleries and rooms rose behind this huge canopy. The priests with their white robes, the meagre, half-naked Egyptians with their pleated aprons and headcloths, the images of beasts and the wonderfully-painted houses in this quarter of the city, particularly attracted Hadrian's attention and made him ask many questions, not all of which could Pollux answer. Their walk which now took them farther and farther from the sea extended to the extreme south of the town and the shores of lake Mareotis. Nile boats and vessels of every form and size lay at anchor in this deep and sheltered inland sea; here the sculptor pointed out to Hadrian the canal through which goods were conveyed to the marine fleet which had been brought down the river to Alexandria. And he pointed out to the Roman the handsome country-houses and well-tended vineyards on the shores of the lake. "The bodies in this city ought to thrive," said Hadrian meditatively. "For here are two stomachs and two mouths by which they absorb nourishment; the sea, I mean, and this lake." "And the harbors in each," added Pollux.
