The French word "Vitrail" translates in English as "Stained Glass". This I learned today reading an article on the piece Gerhard Richter created for the Cologne Cathedral.
While "Stained Glass" is a technically accurate description of the process involved, it seems to miss the whole point, which is less about technique than beauty. By contrast, Richter's piece, inspired by his Color Charts
, is an essentially mechanical composition, relying on mathematics rather than human inspiration; And yet, the result is strangely beautiful, in a way somewhat similar to Bach's music.
Addendum: I could not find what specific function Richter used to create the piece, and would be really interested to know! What I found out is that I there were some concerns
that the random patterns would display inappropriate images...
