slightly ground on one side so as to prevent
the curiosity of any person upon the roof.
This glass was divided by cruciform bars of
copper, and secured by what might be termed
turning buttons of the same metal.
Of this glass all the fragments remained
at the excavation, a circumstance which
appeared not a little curious to those who
imagined that its use was either unknown,
or very rare, among the ancients, and did
not know that a window of the same kind
had been found in the baths of the villa of
Diomedes.
Glass seems to have, at first, been brought
from Egypt, and to have in fact received its
name of vaXot from the Coptic. Crystal, *ju-
(TT-aXXof, or the permanent ice of the ancients,
originally designated the natural stone itself.
It is said to have been little known in Rome
before 536, U.C., but this would give ample
time for its use at Pompeii long before its
destruction.
There are few subjects on which the
learned seem to have been so generally mis-
taken as that of the art of glass-making
