Golden Horn from the Sea of Marmora

He also constructed another harbour on the southern side of the city, placing it in the hollow ground below the heights on which the Hippodrome stands, and thus provided for the convenience and safety of ships that found it difficult to make the Golden Horn from the Sea of Marmora, in the face of the northern winds that prevail in the Bosporus. The harbour was first known as the New Harbour and the Harbour of Julian, but, in the sixth century, it was also named the Harbour of Sophia or the Sophias, in view of extensive repairs made at the instance of the Empress Sophia, the consort of Justin II. The basin of the harbour can still be traced in the configuration of the ground it once occupied, where its memory is preserved by the present name of the locality—Kadriga Limani, the Port of the Galley.

At the head of the harbour Julian built a portico, a crescent in shape, and therefore spoken of as the Sigma, from its resemblance to the curved form of that letter in the Greek alphabet. Very appropriately the portico became a favourite lounge of the philosophers in Constantinople, and the scene of their discussions. But what Julian doubtless considered his richest and most filial gift to the city of his birth, was the presentation to its public library of his collection of books.

Surmounted respectively

Valens, the next Emperor concerned with the growth of the city, gave special attention to the water-supply of Constantinople—always a serious question owing to the comparative scarcity of water in the immediate neighbourhood. The picturesque aqueduct which, with its double tier of arches gar-landed with ivy, still transports water across the valley between the hills surmounted respectively by the Mosque of Sultan Mehemet and the War Office, was built in this reign. It was an addition to the system of water-supply provided by Constantine; a system which, probably, had previously served the town of Byzantium, and which he only extended and improved. Near the eastern end of the aqueduct a splendid public fountain was placed.
