Column of Marcian

The Column of Marcian (Turkish: Kıztaşı, meaning "Column of the girl") is a Roman honorific column erected in Constantinople in 455 dedicated to the Emperor Marcian. It is made of red-grey Egyptian granite, in two pieces. The basis is quadrilateral, formed by four slabs in white marble, decorated with Chi-Rhos inside medallions on three faces, and two genii (who account for the Turkish name of the column) holding a globe. The column is topped by a Corinthian capital (decorated with aquilas) probably a basis for a statue of Marcian in imitation of the Column of Trajan and the Column of Marcus Aurelius in Rome, which definitely were topped by statues of the emperor they commemorated.
