And [a history] of its [glass] meaning
Glass as building material has always meant connection to the outside world, often at a cost of warmth (or dryness). Two papers/essays discussed in past architectural theory classes covered some of the evolving meaning of glass and of windows in the 20th century. Type and its Transformation by Alan Colquhoun discusses the various types of windows used by Le Corbusier, in terms of their meaning and function. In Richard Neutra and the Psychology of the American Spectator Sylvia Lavin discusses two churches in Southern California – one a drive-in ministry and the other for a televangelist.
