An early reference in literature to glass is mentioned in De opificio Dei, chapter VIII (p. [131-132]). The passage has been translated as "... it is the mind which, through the eyes, sees those things which are placed opposite to it, as though through windows covered with pellucid crystal [vitro in text] or transparent stone". Prior to the use of glass, Greek and Roman windows had been made from transparent stone (mica, talc, etc.).
