Barbaro (p. 733) refers when, speaking of the two towers, on the opposite sides of the entrance to the Golden Horn, which supported the chain, he says, “Etiam una tore per ladi de la zilade, zoè una de la banda de Constantinopoli, l’altra de la banda de Pera, le qual tore vignia a far defexa assai.” Footnote 830: N.

Footnote 833: Dr. Paspates (Πολιορκία καὶ Ἄλωσις τῆς ΚΠ., p. 63) thinks the tower stood beside the Offices of the Board of Health, between the Galata Bridge and the Galata Custom House. He grounds this opinion on the existence of old ruins at that point. But the chain would never be placed aslant the harbour, as this view implies. Footnote 834: Theophanes, p. 609.

Footnote 844: Pages 254, 255, Ἐδόθη φυλάττειν τὸν πύργον τὸν ἐν μέσω τοῦ ῥεύματος, τὸν φυλάσσοντα τὴν εἴσοδον τοῦ λιμένος, καὶ ἦν ἀντικρὺς τῆς πύλης τῆς βασιλικῆς. Footnote 845: Page 259. Dr. Paspates, in his work on the siege of the city (Πολιορκία καὶ Ἂλωσις τῆς Κωνσταντινουπόλεως, p. 141), represents the Hill of St. Theodore and the battery upon it as commanding the Bay of Cassim Pasha. This, however, is in harmony neither with the statements of Phrantzes, nor with local configuration. The requirements of the case are met by the supposition that the Hill of St. Theodore was the ridge to the north-east of Top Haneh, and that the Sultan’s battery stood nearer the Bosporus than the present Italian Hospital. Cf. Zorzo Dolfin, s. 44: “Acceso el Turcho da disdegno, da i montè orientali de Pera penso a profondar con machine e morteri, o trar quelle de la cathena. Mezzo adonque le bombarde a segno dal occidente” (_i.e._ aiming towards west), “se sforza con bombardieri profundar le naue.” Footnote 846: Page 259. Footnote 847:
