The portico forming the next illustration was a long time considered the only remaining portion of a temple dedicated to the Emperor Augustus, but it is now clearly established as having been one of the entrances to a market-place. This idea, suggested to the mind of Stuart, by certain minute yet well marked variations in the proportion of the columns from those devoted to sacred purposes, has been sustained by research, and finally demonstrated to be correct by the discovery of an inscription which has put the question at rest for ever. In one of these the names of two prefects of the market are preserved; and another, still perfect, is an edict of Hadrian respecting the duties to be levied on certain articles of consumption, and regulating the sale of oils, &c. Nothing can be more picturesque than the present condition of this portico, the latest specimen of the pure Greek Art. Its coloring is rich and varied, while its state of ruin is precisely that in which the eye of the painter delights, sufficient to destroy all hardness or angularity, yet not so great as to rob it of one element of grandeur. [Illustration: ENTRANCE TO THE MARKET-PLACE: FORMERLY SUPPOSED TO BE PART OF A TEMPLE DEDICATED TO AUGUSTUS.] The building called the Monument of Philopappus, despite its somewhat fantastic elaboration of detail, is very remarkable and interesting; it was created either during the lifetime, or as a memorial immediately after his death, to Caius Julius Antiochus Philopappus, a descendant of the royalty of Syria, and an adopted citizen of Athens. It consists of a basement supporting a pilastrade of semi-circular form, and presenting upon its concave surface three niches, containing sitting statues, and three recesses richly ornamented with the representation in strong relief of a Roman triumph. Upon the basement also were various sculptures in honor of the Emperor Trajan. These, and, indeed, all the decorative sculpture, &c., profusely lavished upon this building have suffered greatly. The two remaining statues are much dilapidated. From this point a magnificent view of the Acropolis is obtained, and few are the sights presented to the traveller, which surpass in historic interest or actual beauty that meeting his eye, to whichever point of the compass he may turn when standing at the foot of this remarkably picturesque monument.
