may refer to victories of Theodosius in 381, but more probably carries us back as far as the time of Claudius Gothicus and the battle of Nissa, 269. It is fifty feet high, and is said to have supported a golden statue of Theodosius. According to legend a pillar-saint lived on it for twenty years. Certainly it was used for a grimmer purpose, for the Latins in 1204 dashed from its summit the usurper Alexius Mourtozouphlos. The column of Marcian, not far from the Etmeidan, where the Janissaries were destroyed, is hard to find; it is in a garden belonging to a Turkish private house. It is of granite with a marble capital. The column of Arcadius, of which only the base remains, is at Avret Bazar on the seventh hill. Next to the columns the most interesting antiquities are the aqueducts and cisterns. The aqueduct of Valens, built in 366 of stone from the walls of Chalcedon, is a conspicuous object in the view from the hill of Pera. It has been constantly repaired and restored, and it still carries water. It now extends from near the east of the mosque of Mohammed II. very nearly to the Seraskerat. The way from the mosque back to the bridge passes under it, and gives a good view of its construction and its picturesque, overgrown, half-ruined state. This and the other aqueducts (one of which may be seen near Edirnè Kapoussi) brought water from the distant hills, which was stored in vast cisterns, many of which still remain. Three at least are worth a visit. The most beautiful are the work of Philoxenus; and chief is that which the Turks call Yeri Batan Serai--the underground cistern--but more generally known is that fancifully called Bin Bir Derek, cistern of 1001 columns. I may repeat what I have said of them elsewhere.[66]
