These ruined cities contain amphitheatres more or less spacious, and generally in a good state of preservation, temples, aqueducts, and sepulchral monuments, together with numbers of lesser buildings, the dwelling houses of the inhabitants. The ruins of Christian churches are also found in many places, and in one instance a large and elegant cathedral; the purposes of these are satisfactorily made out by their inscriptions; and the date of their erection, when not otherwise known, may be fixed by their style of architecture. The most numerous as well as the most interesting monuments of these ancient cities, are their sepulchres. In some instances where a mountain or high rock is contiguous, it is pierced with thousands of tombs, presenting an appearance similar to Petræa in Idumea, sometimes called the City of the Dead. The roads in all directions are lined with tombs and sarcophagi, many of them covered with elaborate sculptures and inscriptions. It is by means of the latter, which abound and which exist in a fine state of preservation, that the names of the cities are identified and other historical facts brought to light. The following is a translation of the most common form of sepulchral inscription. "THIS TOMB APOLLONIDES, SON OF MOLISSAS, MADE FOR HIS WIFE AND CHILDREN: AND IF ANY ONE VIOLATES IT, LET HIM PAY A FINE." Coins too are found, which possess considerable historic interest. In architecture, we find excellent specimens of the several Grecian orders, exhibiting both the perfection and declension of the art. The works of Sir Charles Fellows abound in architectural representations. A pointed arch was discovered by Lieut. Spratt and Professor Forbes in the interior of a tomb (a sketch of which is given) among the ruins of Antiphellas. This conclusively shows, that this peculiar form of the arch was not first introduced with Gothic architecture, as has been generally believed, but belongs to a period anterior to the Christian era. An inscription in the Lycian and Latin was found on the monument. The language of the ancient Lycians is an important discovery which has resulted from these researches. A bilingual inscription in Lycian and Greek first led to the key, and similar inscriptions, subsequently discovered, have furnished sufficient materials for ascertaining the values of the several letters of the alphabet, which consists of twenty-seven letters, two of which are still doubtful. Able disquisitions on the language have been written by Mr. Sharpe and Professor Grotefend.
