The division of Western Mediaeval Architecture into the two schools of Romanesque and Gothic presents a parallel case. It is now realised that no logical separation can be made between the two so-called styles. Similarly we may continue to speak of the Classic Roman style and of the Byzantine style, although the two really belong to one great era in the history of art.

The examples he produces seem rather octagons carried up from the ground to give a clearstory under the dome than true drums interposed between the dome and its pendentives.

JOHN THE BAPTIST OF THE STUDION, EMIR AHOR JAMISSI The mosque Emir Ahor Jamissi, situated in the quarter of Psamathia, near the modern Greek church of S. Constantine, and at short distance from the Golden Gate (Yedi Koulé), is the old church of S. John the Baptist, which was associated with the celebrated monastery of Studius, [Greek: hê monê tou Stoudiou]. It may be reached by taking the train from Sirkiji Iskelessi to Psamathia or Yedi Koulé.[35]
