observing, he began to repair the _Aqueduct_ of _Valentinian_, which continued in good Order, till the Reign of _Heraclius_, when it was demolished by the _Avares_. Upon this he sent for Workmen from many Places to rebuild it; from _Asia_ and _Pontus_ he had a Thousand Builders, and two hundred White-washers; from _Greece_ five hundred Brick-makers, and from _Thrace_ a Thousand Day-labourers, over whom there presided a Nobleman, and some of the principal Men of the City, as Surveyors of the Works. When the _Aqueduct_ was finished, the City was again supplied with Water, which was conveyed into the Town through a Passage lying between the ninth and the tenth Ward. There are many subterraneous _Aqueducts_ which run through six of the Hills, but the _Aqueduct_ of _Valentinian_ has its Course above Ground, which the Historians, who have wrote of the _Actions_ of _Andronicus_ tell you, passed through the Great _Forum_, that the Water of it was clear and pleasant, that it was repaired and enlarged by _Andronicus_ himself, and that he encreased its Current by the River _Hydrales_. At the Spring-head, from whence this _Aqueduct_ arose, he built a Tower and a Palace, where he used to divert himself in the Summer. He also brought the Water from the same River into the _Blachernæ_, which is a Part of the _Suburbs_. The Tower was ruined by _Isacius_ his Successor, in pure Resentment to his Memory. We are told by _Procopius_, that _Justinian_ repaired the Church of _Achatius_, when injured by Time; that he placed white Marble Pillars round it, and that he paved and incrusted the Sides of it with the same kind of Marble, so that the whole Building was beautifully white. There were two _Portico’s_ adjoyning to the Church, one which opening to the _Forum_, is encompassed with Pillars. This Passage is not inserted in the printed Edition of _Procopius_, which induced me the more to take Notice of it here. _Cedrinus_ writes, that the Church of St. _Achatius_ stood in a Place called the _Heptascalum_; others say, that it stood in the _Scala_; but no body at present knows where that Place was. However, if any one hereafter should have the Curiosity to enquire where this Church stood, I would advise him to take along with him the following Direction. Let him enquire where the great House stands, which Historians call the _Carya_, because there stands in the _Area_ of it a Nut Tree, upon which, they tell you, that _Achatius_ was put to Death, and upon that Occasion, that a Church was built in Memory of him, which some think, was situate in the _Neorium_, because they have seen it in some Authors, that the Image of St. _Achatius_, made with Glass Stones, and inlay’d with Gold, was placed in the Church of the _Neorium_. But the Person of whom this is spoke was another _Achatius_, who, not only, as many Historians, but as _Suidas_ the Grammarian tells us, was Bishop of _Constantinople_ in the Time of _Leo Marcellus_, but a Man of so proud
