are all of white Marble, and I look upon them to be the largest in the World. The other six support a _Portico_, which runs round the Top of a large Building. The upper Part of the _Portico_ is adorned with Marble elegantly variegated, and equal to that of the Columns, and is furnished with an infinite Variety of curious Statues. I am of Opinion, that _Justinian_ did not build this _Senate-House_, but that he rebuilt the old _Senate-House_, which was burnt down by the Fire, which consumed the Church of St. _Sophia_, and the Baths of _Zeuxippus_. For _Sozomen_ writes, that _Constantine_ the _Great_ built the Great Council-Hall, which was called the _Senate-House_, and ordered it to be held in equal Dignity, and honoured it with the same publick Celebration of the Feast of the _Calends_, with that of antient _Rome_. He tells us where this great Court stood, when he writes, that the silver Statue of _Eudoxia Augusta_ was placed upon a _Porphyry_ Pillar, on the South Side of the Church of St. _Sophia_, beyond the high Pulpit, which faces the _Senate-House_. _Socrates_ tells us, that it was neither erected near, nor at any considerable Distance from the Church of St. _Sophia_; but beyond the broad Way, as _Suidas_ observes, which runs between them both. _In the Tribunal of the Palace_, says he, _stood the Pillar of_ Eudoxia, _the Wife of_ Theodosius. The Treatise _of the antient Description of the Wards_ places the Senate-House, the _Tribunal_ with _Porphyry_ Steps, and the _Basilica_, all in the same _Ward_. _Sozomen_ clearly points out the Situation of the _Senate-House_, where he says, that when a Tumult arose concerning the Expulsion of St. _Chrysostom_, the great Church was all on a sudden in a Blaze, which burnt down the Buildings upon the Walks, and the Great _Senate-House_, lying to the South of them. There are some Remains of the Walls of the _Senate-House_ still standing, southerly of the Church of St. _Sophia_, beyond the Way that leads from the Imperial Gate to the _Forum_ of _Constantine_.
