fashion of domestic architecture. In almost every house there is some
difference in detail from the rest, but the principal outline is the
same in all. In all you find the hall, the tablinum, and the peristyle,
communicating with each other; in all you find the walls richly painted;
and all the evidence of a people fond of the refining elegancies of
life. The purity of the taste of the Pompeians in decoration is,

imitating trees, birds, temples, etc., in perspective--a meretricious
delusion which the graceful pedantry of Pliny himself adopted, with a
complacent pride in its ingenuity.

But the house of Glaucus was at once one of the smallest, and yet one of
the most adorned and finished of all the private mansions of Pompeii: it
would be a model at this day for the house of 'a single man in
Mayfair'--the envy and despair of the coelibian purchasers of buhl
and marquetry.

You enter by a long and narrow vestibule, on the floor of which is the

apart for the reception of visitors who neither by rank nor familiarity
were entitled to admission in the penetralia of the mansion.

Advancing up the vestibule you enter an atrium, that when first
discovered was rich in paintings, which in point of expression would
