$H Aqua‑tint or Aquatint. Engraving
|
Aqua‑tint. A m=
ethod of
engraving with the help of mastic. (Consult
Fielding's "Art of Engraving.") (18=
83m1) |
|
Aquatint. (Engrav.) A process of engr=
aving
by which sepia drawings can be reproduced with great accuracy. The copper
plate, before being exposed to the action of the acid, is covered by powd=
ered
mastic. This prevents the aqua‑fortis f=
rom
acting upon it, and a mottled surface is thus produced. (1891a1) |
|
Aqua-tint. A kind of engraving which imita=
tes
drawings executed in India-ink, bistre, and sepia, very successfully. The=
peculiarity
of this method of engraving consists in sprinkling the copper-plate with
powdered mastic, or some similar substance, which takes a granular form, =
so as
to prevent the AQUA-FORTIS from acting upon the copper where the particle=
s of
the mastic adhere; by this means the copper is corroded only partially, a=
nd
in the interstices between the grains of mastic; the resulting effect exa=
ctly
resembles that of a wash of India-ink. * * The details of th=
is, and
other processes in the art of engraving, may be found in Fielding's Art of Engraving.(1855f1)=

$H Aqueduct.
|
Constructions either above or under ground employed to
conduct water. Aqueducts of Roman construction, some of which are still in
existence, are absolute monuments of art, and in some cases harmonise
wonderfully with the lines of the landscape. In modern times aqueducts are
built from the designs of engineers, and are as a rule nothing more than
water‑pipes of immense girth. They are generally carried underground
that they may escape the frost in winter and that the water they convey m=
ay
be kept cool in summer. (1891a1) |
|
Gen. (aqua,
water, and duco, to lead). An=
artificial
canal for conveying water from one point to another, and often to a
considerable distance from the source. Many ancient nations have executed
works of this description, but the Roman aqueducts are especially celebra=
ted.
The most perfect is that which still exists, in a ruined state, over the
river Gard, near Nismes in the South of France, called Pont‑du̴=
9;Gard.
(Fig. 36.) Aqueducts were often discharged into reservoirs. Fig. 36. Pont‑du‑Gard, a Roman
aqueduct near Nismes. (Restored) (1883m1)
