Ea ambage Chalcedonii monstrabantur quod priores illuc advecti, prævisâ locorum utilitate pejora legissent Tacit. Annal. xii. 63.] The harbor of Constantinople, which may be considered as an arm of the Bosphorus, obtained, in a very remote period, the denomination of the _Golden Horn_. The curve which it describes might be compared to the horn of a stag, or as it should seem, with more propriety, to that of an ox. 11 The epithet of _golden_ 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 11 (return) [ Strabo, l. vii. p. 492, [edit.
