Pompeii have disclosed. A corridor ran round the court supported by
pillars, from which the rooms opened. In a well-defended town like
Silchester the houses were usually built on three sides of the court;
but the country villas, which had occasionally to be fortified against
the attacks of wandering bands of outlaws and wild Britons, and the
inroads of savage beasts, were usually built on all the four sides of
the square court. They were usually of one story, although the existence
of a force-pump in Silchester shows that water was laid on upstairs in
one house at least. As the wells were less than thirty feet deep, a
force-pump would not be needed to lift the water to the earth-level.
Hence in some houses there must have been some upper chambers, a
conclusion that is supported by the thickness of the foundations, which
are far more substantial than would be required for houses of one story.
The rooms were very numerous, often as many as sixty or seventy, and
very bright they must have looked decorated with beautiful marbles and
stuccoes of gorgeous hues, and magnificent pavements, statues and
shrines, baths and fountains, and the many other objects of Roman luxury
and comfort. The floors were made of _opus signinum_, such as the
Italians use at the present day, a material composed of cement in which
are embedded fragments of stone or brick, the whole being rubbed down to
a smooth surface, or paved with mosaic composed of _tesserae_. In
whatever land the Roman dwelt, there he made his beautiful tesselated
pavement, rich with graceful designs and ever-enduring colours,
representing the stories of the gods, the poetry of nature, and the
legends of the heroes of his beloved native land. Here we see Perseus
freeing Andromeda, Medusa's locks, Bacchus and his band of revellers,
Orpheus with his lyre, by which he is attracting a monkey, a fox, a
peacock, and other animals, Apollo singing to his lyre, Venus being
loved by Mars, Neptune with his trident, attended by hosts of seamen.
