’Tis attested by _Eusebius_, That _Constantine_ the _Great_ built the Church of the _Apostles_ to a great Heighth, that he incrusted it with all Sorts of variegated Marble, which cast a beautiful Lustre from Top to Bottom; that he adorn’d it with small gilded Roofs, and cover’d it with Plates of Brass deeply gilt, which cast a blazing Reflexion to a great Distance. The upper Part of this venerable Structure, was curiously wrought all round it with Brass and Gold, and was enlightned with Abundance of Lattices and Windows. Round the Church there was a fine Court lying open to the Air. The _Portico’s_ which enclos’d it, stood in a Quadrangular Manner. Near the _Portico’s_ stood the Palace, the _Bagnio’s_, the Cloysters, and many other Houses and Buildings belonging to the Ecclesiasticks, and other Ministers of the Church. These bountiful Benefactions has the pious Emperor handed down to Posterity in Memory of the _Apostles_ of the blessed Saviour of Mankind, to whom also he consecrated twelve Purses of Gold. The Coffin in which he intended to be buried after he was dead, was plac’d by his Order in the Body of the Church, and guarded with the twelve _Apostles_ in Effigy. ’Tis added by _Socrates_, that the Body of _Constantine_ lying in a golden Coffin, was brought into the City by his intimate Friends, and buried in the Church of the _Apostles_. I am inclin’d to believe, that _Zonaras_ never read _Eusebius_, when he tells us, that ’twas buried in the Cloyster of the Church of the _Apostles_, which, he says, was built by _Constantius_ for the Interrment of his Father. Near the broad Way which stretches itself along the Top of the _Promontory_, from the Church of St. _Sophia_, to the Gate of _Adrianople_, (hard by the Place where stood the Church of the _Apostles_,) there is shewn to this Day, a Coffin made of _Porphyry_ Marble, empty; and without a Cover, ten Foot long, and five Foot and a half broad, which the _Greeks_ and _Turks_ say, was the Coffin of _Constantine_ the _Great_; but I cannot vouch for the Truth of it: Yet the Authorities of _Socrates_ and _Eusebius_ seem to be somewhat doubtful, who tell us, that he was buried in a golden Coffin, unless perhaps the golden Coffin was inclos’d in that of the _Porphyry_ Marble. _Zonaras_ is of Opinion, that _Theodora_, the Wife of _Justinian_, built the Church of the _Apostles_; and adds, that there was anciently in the same Place a _Church_ of the _Apostles_, but much Inferior in Beauty and Magnificence to that which stands at present, on the same Ground. _Procopius_ says, that there had been for some Ages, a Church at _Constantinople_ which was much impair’d by Time, and likely to fall, which _Justinian_ order’d to be taken down, rebuilt, and enlarg’d, and made in the Figure of a Cross, the Body of the Church pointing East, and West, and the Part crossing it, North, and South. This Church is well wall’d, and adorn’d within with Ranges of Pillars standing one above another: _Evagrius_ therefore
