After some rest, I proceeded to stroll about,--first of all to the great Temple of the Sun, on a rising ground to the west of the great colonnade, which, besides the columns along all the sides of the edifice, has a conspicuous portico in front, consisting of twelve magnificent Corinthian columns, a few of which are fallen. Thence I walked to the Naumachia, near the southern extremity of the city, (that by which we had arrived,) and found this in good condition, with the seats remaining, and the channel well defined which conveyed water for the exhibitions from the above-mentioned spring. The form is a long oval, flattened at one end. In passing once more between the double line of Corinthian columns, I counted fifty-five of them standing, besides fragments and capitals of the missing ones lying on the ground. From this I diverged at right angles, through a street of small public buildings, towards the bridge over the stream, (and this I called Bridge Street--part of the pavement still remains, consisting of long slabs laid across the whole width from house to house;) then upon the bridge, as far as its broken condition would allow, and returned to my home--everywhere among scattered fragments of entablature; numerous altars entire, and sculptured with garlands; also broken buildings, with niches embellished inside with sculptured ornament. In all my exploration, however, I found no statues or fragments of statues--the Mohammedan iconoclasts had long ago destroyed all these; but there were some remains of inscriptions, much defaced or worn away by the work of time. The natural agencies by which the edifices have come to ruin seem to be--first, earthquakes; then the growth of weeds, thorns, and even trees, between the courses of stone, after the population ceased; or rain and snow detaching small pieces, which were followed by larger; also sometimes a sinking of the ground; and besides these common causes of decay, there comes the great destroyer--man. Yet nature is always picturesque, even after the demolition of the works of human art or genius; and it is pleasing to see the tendrils, leaves, and scarlet berries of the nightshade playfully twining among the sculptured friezes which are scattered about in every position but straight lines; or other plants between the volutes, rivalling the acanthus foliage of the classic capitals. Sunset: a beautiful landscape all around; and a pretty view of the travellers' tents, the Arabs, and the cattle below me. After dinner I walked by starlight along the Ionic colonnade, which is a further continuation northwards of the Corinthian, and found nearly the whole length, with the intermediate pavement, remaining, consisting of squares about two feet in length, laid down in diamond pattern.
