Returning by boat along the walls of the city, I observed its crooked figure and posture to the sea; and noted also the several square towers variously interspersed at unequal distances, each bearing an inscription much to the same purport, as may be seen by the following copy, which I took of them in the boat. On a tower near the _Porta Janicula_: ΠΥΡΓΟΣ ΒΑϹΙΛΕΙΟΥ ΚΑΙ ΚΩΝϹΤΑΝΤΙΝΟΥ ΠΙϹΤΩΝ ΕΝ Κ̅Ω̅ ΑΥΤΟΚΡΑΤΟΡΩΝ On a tower in that part of the wall, which includes the _seraglio_: ΠΥΡΓΟϹ ΘΕΟΦΙΛΟΥ ΜΕΓΑΛΟΥ ΕΝ ΚΥΡΙΩ ΒΑϹΙΛΕΩϹ ΚΑΙ ΑΥΤΟΚΡΑΤΟΡΟϹ. Round the same _seraglio_: ΠΥΡΓΟϹ ΘΕΟΦΙΛΟΥ ΕΝ ΧΡΙϹΤΩ ΑΥΤΟΚΡΑΤΟΡΟϹ About the same place: ΠΥΡΓΟϹ ΘΕΟΦΙΛΟΥ ΚΑΙ ΜΙΧΑΗΛ ΠΙϹΤΩΝ ΕΝ Κ̅Ω̅ ΑΥΤΟΚΡΑΤΟΡΩΝ. June xvii. About midday I saw the ceremonies of the _dervíse_ convent of the order called _Meuleví_ at _Pera_, consisting of their _namáz_, somewhat longer than is ordinary at other times and places. After which followed a sermon, that is, a gallimaufry of dreams and nonsense, pronounced by the prior of the convent, as he sat cross-leg’d on the seat of a two elbowed wooden chair. This was succeeded by their music in a gallery over the door; during which about fourteen _dervíses_ led up a religious dance in the area of their theatre (for such is the figure and contrivance of it) in which they turn round almost in the same place with incredible swiftness, without either weariness or giddiness, for the space of half an hour. By this exercise their brain is so habitually fortified against dizziness, that one of them was able to hand upon the half moon of a _minarée_ belonging to the _Solymanjá_, and from thence to salute the _Grand Signior_ at his palace of _Cushcui_, at the same time firing off a pistol, and drinking a dish of coffee. About five this evening I took leave of Mr. Goodfellow, and embarked upon a boat manned with seven hands, which I had hired for ten dollars to transport my self, my horse, and two servants from _Galata_ to _Montagnia_, being the space of two leagues. When having a fair wind, which by degrees increased, and exposed me to the fatigue of a nauseous sea sickness, after midnight I entered the two capes, which form the _Sinus Cianus_. In this bay is that famous fountain mentioned by _Virgil_: _Hylan nautae quo fonte relictum_ _Clamassent; cum littus, Hyla, Hyla, omne sonaret[89]._ June xviii. By six this morning I landed safe at _Montagnia_, a small Turkish town, which seems to have been the _Apaméa_ of the antients; _Cius_, or _Prusa ad Arganthonium_, being now a little village, that lies farther towards the utmost corner of the bay. Here I hire a guide and horse to carry my self, servants, and baggage to _Prusia_, antiently _Prusa ad Olympum_, where by God’s blessing I arrive safely about midday; and taking up my lodgings in the great silk _kane_, I there determine to repose till to morrow morning.
