Note 385 — Chapter VII
Reading edition
The fine colour then given to stained glass in Europe was derived from the old mosaics, which were pounded and laid upon the glass, and thus passed into the furnace. See Theophilus Divers, Artium Cedula. Immense must have been the destruction of ancient relics through this practice, to which the Moorish mosaics were subject, as well as those of Rome and the glass of the Phœnicians.
