Note 59 — LXXX. A Dissertation on the Antiquity of Glass in Windows. In a Letter to the Rev. Tho. Birch, D. D. Secret. R. S. By the Rev. John Nixon, M. A. F.R.S.
Reading edition
Salmasius, speaking of the custom of adorning chambers with glass, says—Quod proximè ætatem suam incepisse fieri narrat Plinius. Quum M. Scaurus——Ex. Plin. tom. II. p. 854.
I do not find this expresly asserted by Pliny: but it might have been so in fact. This fashion indeed was not begun till after Agrippa had built his thermæ: but if we suppose that to have been even as late as his third consulship, viz. ante Christ. 27. (Helvicus), when he erected the Pantheon (or at least its portico), near adjoining to those thermæ, there would have been sufficient room, from that period to the birth of Pliny (viz. anno Christi 24), for the introduction of this usage.
