the Romans threw from one to another as a gentle exercise of the
body.--(2) A leather purse or bag.--(3) A pair of bellows, consisting
of two inflated skins, and having valves adjusted to the natural
apertures at one part for admitting the air, and a pipe inserted into

FONS (κρήνη), a spring of water, and also an artificial fountain,
made either by covering and decorating a spring with buildings and
sculpture, or by making a jet or stream of water, supplied by an
elevated cistern, play into an artificial basin. Such fountains
served the double purpose of use and ornament. They were covered
to keep them pure and cool, and the covering was frequently in the
form of a monopteral temple: there were also statues, the subjects
of which were suggested by the circumstance that every fountain was
sacred to some divinity, or they were taken from the whole range of
mythological legends. A very large proportion of the immense supply
of water brought to Rome by the aqueducts was devoted to the public
fountains, which were divided into two classes; namely, _lacus_,
ponds or reservoirs, and _salientes_, jets of water, besides which
many of the castella were so constructed as to be also fountains.
There were also many small private fountains in the houses and villas
of the wealthy.
