I will now explain the Emperor’s works to afford an abundant supply of water to the city. In summer-time the imperial city used for the most part to suffer from scarcity of water, although at other seasons it had sufficient; for at that time, in consequence of the drought, the fountains flowed less plenteously than at other seasons, and supplied the aqueducts of the city very sparingly. Wherefore the Emperor devised the following plan. In the Portico of the Emperor, where the advocates, and magistrates, and other persons connected with the law transact business, there is a very lofty court of great length and width, quadrangular in shape, and surrounded with columns, which is not constructed upon an earthen foundation, but upon the rock itself. Four porticos surround this court, one upon each side of it. The Emperor Justinian excavated one of these porticos, that upon the south side, to a great depth, and stored up there the superfluity of water from the other seasons for use in summer. These cisterns receive the overflow from the aqueducts, when they are too full of water, giving them a place to overflow into, and afford a supply in time of need when water becomes scarce. Thus did the Emperor Justinian arrange that the people of Byzantium should not want for sweet water. He also built new palaces elsewhere, one in the Heræum,[32] which is now called the Hiereum, and in the place called Jucundiana. I am unable to describe either the magnificence or exquisite workmanship, or the size of these palaces in a manner worthy of the subject. Suffice it to say that these palaces stand there, and were built in the presence and according to the plans of Justinian, who disregarded nothing except expense, which was so large that the mind is unable to grasp it. Here also he constructed a sheltered harbour, which did not exist before. Finding that the shore was exposed on both sides to the winds and the violence of the waves, he arranged a place of refuge for mariners in the following manner: he constructed what are called chests, of countless number and of great size, flung them into the sea on each side of the beach in an oblique direction, and by continually placing fresh layers in order upon the others, formed two walls in the sea opposite to one another, reaching from the depths below to the surface of the water on which the ships sail; upon this he flung rough stones, which when struck by the waves break their force, so that when a strong wind blows in the winter season, everything between these walls remains calm, an interval being left between them to serve as an entrance for ships into the harbour. Here also he built the churches which I formerly mentioned, and also porticos, market-places, public baths, and everything else of that sort; so that this palace in no respect falls short of that within the city. He also built another harbour on the opposite continent, in the place which is called after the name of
