en was expressive of the riches which every wind
wafted from the most distant countries into the secure and capacious
port of Constantinople. The River Lycus, formed by the conflux of two
little streams, pours into the harbor a perpetual supply of fresh water,
which serves to cleanse the bottom, and to invite the periodical
shoals of fish to seek their retreat in that convenient recess. As the
vicissitudes of tides are scarcely felt in those seas, the constant
depth of the harbor allows goods to be landed on the quays without the
assistance of boats; and it has been observed, that in many places the
largest vessels may rest their prows against the houses, while their
sterns are floating in the water. [12] From the mouth of the Lycus to
that of the harbor, this arm of the Bosphorus is more than seven miles
in length. The entrance is about five hundred yards broad, and a strong
chain could be occasionally drawn across it, to guard the port and city
from the attack of a hostile navy. [13]

antlers are now broken off; or, to speak less figuratively, most of the
recesses of the harbor are filled up. See Gill. de Bosphoro Thracio, l.
i. c. 5.]

the Acropolis near the modern Kiosk, to the tower of Galata; and was
supported at convenient distances by large wooden piles.]
Between the Bosphorus and the Hellespont, the shores of Europe and Asia,
receding on either side, enclose the sea of Marmara, which was known to
the ancients by the denomination of Propontis. The navigation from the
issue of the Bosphorus to the entrance of the Hellespont is about one
hundred and twenty miles.
Those who steer their westward course through the middle of the
Propontis, may at once descry the high lands of Thrace and Bithynia,
and never lose sight of the lofty summit of Mount Olympus, covered with
eternal snows. [14] They leave on the left a deep gulf, at the bottom
of which Nicomedia was seated, the Imperial residence of Diocletian; and
they pass the small islands of Cyzicus and Proconnesus before they cast
anchor at Gallipoli; where the sea, which separates
