Returning to the ground at Athens, we find the Areopagus on the north-western descent of the Acropolis, and forming an appendage to it: a hollow to the south-west of these eminences, separates these from a long hill, divided into three summits, now called the Musæum, the Pnyx, and the Lycabettus; for the first name we have sufficient authority, the second is not so clear, and for the last, I can find no reason, except that we have the name in ancient authors, without knowing to what eminence it was applied, and here is a hill without any other name; but I shall use all these names, and some other doubtful ones, just as if they rested on the most perfect chain of evidence, for the sake of convenience. The Musæum is very nearly as high as the Acropolis; the other summits are lower: on the opposite side of the town, but at a greater distance, the hill of St. George, supposed to be the ancient Anchesmus, overtops them all; and its narrow summit is crowned with a small chapel. To the south-east, on the other side of the Ilissus, our views are bounded by the great, rounded mass of Hymettus; while from various points looking up the stream, we perceive the more lofty, and more picturesquely formed Pentelicus. Across the plain, and the Cephisus, is the long range of Parnes, ending in the lower hills of Corydalus and Aigialos; but if you wish to complete the picture, as seen from the eminences about Athens, you must add to these objects the Saronic gulf, with its surrounding mountains, the islands of Egina and Salamis, the mountains of Megara, Cithæron, the Acropolis of Corinth, and mount Cyllene; names crowded with recollections which spread a charm on every spot over which the eye wanders. The rock here is generally limestone, but not all of one formation; in the bottoms, and on the high mountains, it is united with mica slate. Anchesmus, and the hills about Athens, if not of mountain lime, are perhaps oolitic, though the stone is very hard and compact, and frequently somewhat translucent, and I have not been able to discover any shells in it. There is a conglomerate, where fragments of primitive rocks are united by a calcareous cement, which seems to contain magnesia, and may correspond with our magnesian limestone, while the hills of the Piræus are of a soft calcareous sandstone, containing shells of a much later period. A sandstone at the base of the Musæum is perhaps gray wacke, but I will not detain you on a subject of which I understand so little.
