cc had all its Tides within ornamented with plates of 
“ glafs, Tome of them tinged with various colours, 
<c others of their own natural hue, which was duilcy, 
tc occafioned by the thicknefs of the mafs, of which 
tc they confided *. There were likewife in the fame 
,c apartment, window-frames compofed of marble, 
“ and glazed with laminae of glafs.” But as the Ab- 
bate did not take upon himfelf to afcertain the real 
age of this building, I fhali not pretend to lay any 
greater drefs upon this dilcovery, than I did upon 
the obfervation, for the fake of which I produced it, 
for proving the point I had then in view, viz. that 
the ufage of glafs for windows was (probably) nearly 
of the fame antiquity with that of adorning houfes 
with it. 
I informed the Society -f*, that I had not been able 
to trace up the condrudting of windows with plates 
of glafs, fuch as thefe found at Herculaneum, higher 
than two hundred years fhort of the overthrow of that 
city : but, fome time after, a paifage in Baronius was 
fuggeded to me, which Teemed to carry the antiquity 
of this practice much higher, even to the 42.d year 
of the Chridian ara. It was a quotation £ from 
Philo Judasus, wherein he gives an account of C. Ca- 
* Nam cum laminae craffioris eflent molis, colorem opacum 
nigrantemque reddebant. Vcnuti. This would be the effect of 
the antient glafs, if it was of a coarfer compofition than ours : 
and that it was fo in fa a very eminent critic, both in facred 
and profane literature, thinks, may be collected from St. Paul’s 
words, i Cor. xiii. 12. “ Now we fee, but through a glafs 
“ darkly.”
