for the width of Atrium when viewed from vestibule. The kitchen has
windows opening to the street. In an open court is a permanent
semicircular couch of stone, the _sigma_ of Martial, and so called from
the shape that the Greek letter had at this period acquired. (See notice
on the changes in the Greek alphabet, in the Catalogue of Greek Court,
p. 22). In the Atrium, plants were painted on the wall, as if sprung up
out of the ground. A celebrated caricature painting of the studio of a
portrait painter was discovered by Mazois in this house.
