Upon that site I noticed what I would consider a particularly beautiful example of a canopy that was used for the procession to the altar of repose upon Holy Thursday. It incorporates both beautiful forms, detailing and colour -- even down to the fleur-de-lys upon the staves.
Considering examples like these can be a valuable exercise as they can be of practical assistance to parish priests who are trying to acquire items for their own parishes. As in all the sacred arts, it can very often be important to consider why one example may strike one more positively or negatively than another and determine what elements may lend to the particular dignity or beauty of an item to be used within the context of the sacred liturgy -- or, just as importantly, what does not lend to it.
As an aside, I am always pleased when I see the fuller form of canopy used in processions of the Blessed Sacrament, as there is a certain dignity and particular solemnity that accompanies it, and by correspondence, which speaks to and teaches of the supreme dignity of that which it accompanies.
