The Harbour of the Bucoleon was attached to the Great Palace[988] (τὸ τοῦ παλατίου νεώριον ἑν τῷ Βουκολέοντι) for the convenience of the emperor, who in a city like Constantinople would have frequent occasion to move to and fro by water. Its name was derived from a marble group of a Lion and a Bull upon the harbour’s quay, the lion being represented with his left foot upon a horn of the bull, in the act of twisting his victim’s head round to get at the throat.[989] The harbour, partly artificial, was protected by two jetties from the violence of the winds and waves;[990] and, in keeping with its destination, displayed considerable architectural splendour. Its quay was paved with marble,[991] and adorned with figures of lions, bulls, bears, and ostriches;[992] a handsome flight of marble steps led to the water;[993] and upon the adjoining city walls rose two Imperial villas, known as the Palace of the Bucoleon (τὰ παλάτια τοῦ Βουκολέοντος).[994] Strangely enough, the site of a harbour so prominent, and so fully described, has been a point concerning which students of the topography of the city have widely differed. Dr. Paspates[995] placed the harbour at a distance of 104 feet to the south of Indjili Kiosk, consistently with his opinion that the ruins discovered behind that Kiosk marked the site of the Palace of the Bucoleon.[996] With much learning and ingenuity, Labarte argues that the Harbour of the Bucoleon was in the recess of the shore at Ahour Kapoussi.[997] Von Hammer wavered in his opinion, placing the harbour at one time at Tchatlady Kapou, and at another at Kadriga Limani.[998] And yet to Von Hammer is due the discovery of the evidence that puts an end to all uncertainty on the subject, by showing us that the marble group of the Lion and the Bull, which gave the harbour its name, stood at Tchatlady Kapou. The evidence on the subject is found in a report which Pietro Zen, Venetian envoy to the Turkish Court, sent to his Government in 1532, where he describes the monument at great length, as he saw it after it had been shaken by an earthquake. In quoting this description,[999] Von Hammer, however, not only fails to use it for the settlement of the question at issue, but also omits portions of the report which are of the utmost importance for determining the exact site of the famous group. Dr. Mordtmann, citing Von Hammer, has appreciated the significance of the passage referred to, and employs it more successfully, but with the same omissions.[1000] The original manuscript of the report is preserved in the Marciana Library, among the unpublished Archives of the Venetian Republic,[1001] and the passage with which we are concerned reads to the following effect:
