rently their
_Apartments_; for the _Romans_ had their _Courts_ and _Entries_
magnificent: but the _Greeks_ had only a narrow Entrance, through which
they passed into a _Peristyle_; this _Entry_ had of one Side a Porter's
Lodge, on the other Side the Stables.

The _Apartments_ of these two Nations differed in this, the _Apartments_
of the Women were separate from the _Apartments_ of the Men among the
_Greeks_; insomuch that they Dined apart. They had likewise particular
_Rooms_ reserved for Strangers apart, where they only gave them Lodging,
and never treated them above one Day.

ARTICLE I.

_Of_ Aqueducts.

[Sidenote: _Lib. 8. Chap. 6._]

In Order to the bringing of Waters to Towns and Cities, the Level must
be exactly taken; to the end, it may be known whether the Waters can be
brought thither or no. The Ancients to this end made use of an
Instrument called _Corobates_, which was directed by a Lead, and by
Water, when the Wind hindered them from making use of the Lead.

They brought their Water three several ways; _viz._ by _Aqueducts_, by
Pipes of Lead, and Pipes baked in a _Potter's_ Furnace. They allowed for
the _Channels_ or _Sewers_ of the _Aqueducts_, for every 100 Foot, half
a Foot of Declination or Sloping; and if any Hills were in their way,
they dug through them, making Vents to give Air at convenient Distances.

The Pipes of Lead were at least 9 Foot long; they made them of bended
Sheets or Plates, and of different thicknesses, according to the
Proportion of the greatness of the Pipes; these Pipes had likewise their
necessary Declination or Sloping, and if any Valley was in the way, they
made it equal to the Level with a Wall; they likewise made many Vents,
to give the Water Air, and to know where to mend the Pipes.

The Pipes of _Potter's-Work_, were two Inches thick; they were joyned
together with Mortar mixed with Oil, and when they had _Conde_ or
_Joynt_ to make, they made use of a red Free Stone which they pierced
through, to receive the two Ends of the Pipes.

ART. II.

_Of Wells and Cisterns._

It being remarkt oftentimes that the Water which is under the Earth hath
many bad Qualities, and exhales vapours, which often stifles those which
work in the _Wells_, after that they are dug, & the Water begins to
gather together. The Ancients had this Precaution, to let a Lamp gently
down into it, a
