Twenty publick, and a hundred and twenty private Mills.] At Rome two hundred and fifty four.
A hundred and seventeen Gradus.] At Rome none.
Five Flesh-Markets.] At Rome two only.
Five hundred and sixty Collegiati.] It is apparent that thirty seven of them are omitted in the last Ward. There was no such Office at Rome, yet there were, instead of them, Watchmen divided into seven Companies, whose Business, according to Dion and Suetonius, was much the same with that of the Collegiati.
Sixty five Vico-magistri.] It should be read seventy; for five of them are omitted in the last Ward. At Rome the Number of Collegiati was six hundred and seventy two.
A Porphyry Pillar.] There was no such Pillar, as Cedrinus says, at Rome, tho’ this was brought from thence. Gyllius writes, that this Pillar was made of square marble Stones, and that it stood in the Hippodrom.
Two Pillars with Winding-Stairs in the Inside of them.] There was the same Number at Rome.
One Colossus.] At Rome there were two. ’Tis omitted in the Description of the Wards, as many other Things of Note are.
The Golden Tetrapylum.] Gyllius quotes an unknown Author who will have this Tetrapylum to have been a Quadrangle with Portico’s round it, having Four Gates, and was formerly call’d Quadrivium. The Latines call it a Stadium. But there’s no such Place to be found in the Wards of the City, unless it be the Stadium in the Fourth Ward, which is omitted in the Summary View of the City. Cedrinus, in his Life of Leo Magnus, mentions this Tetrapylum. Evagrius in the twenty eighth Chapter of his third Book tells us, that it was built by the Senator Mammianus, in the Reign of Zeno. He built, says he, two stately Portico’s of exquisite Workmanship, and beautify’d them with a neat glossy Marble. As to the Tetrapylum built by Mammianus, there are not, as Gyllius tells us, the least Remains of it. Victor writes, that there was a Pentapylum in the tenth Ward of Rome.
The Augusteum.] This was the Forum of Augustus.
