John Ruskin,
The Stones of Venice, Volume 1…
“ The relations of the canopy to the statue it shelters, are to be considered altogether distinctly from those of the canopy to the building which it decorates. In its earliest conditions the canopy is partly confused with representations of miniature architecture: it is sometimes a small temple or gateway, sometimes a honorary addition to the pomp of a saint, a covering to his throne, or to his shrine; and this canopy is often expressed in bas-relief (as in painting) , without much reference to the great requirements of the building. ”
