One of the fascinating things to me about art history is the way decorating styles have changed over the millennia. In most cultures decoration—which I’ll just define broadly as little fiddly bits added on to something that don’t really need to be there but make it look nicer—is used to some degree or other. In Europe decoration really reached its height in the Baroque and Rococo periods with decoration getting so elaborate I’m not sure the eye could take it all in, and in a lot of cases there were details that were missed. Once, while I was visiting a late Baroque cathedral in Austria, the tour guide pointed out a carving on the armrest of a pew of a couple in the 69 position, and it probably went unnoticed for a really long time because it was dark wood and there was so much other stuff around it. And eventually there’d be a decline and some movements, particularly in architecture, aimed for more utilitarian designs, such as the Bauhaus which had an aesthetic based on straight lines and little decoration but then moved into singing about Bela Lugosi, but that’s another story.
Even the sparest, least decorated art can also be very emotionally effective. Some people point to Mark Rothko’s large blocks of color and say, “Well, hell, I could do that,” but his paintings can be very haunting and up close reveal a lot of detail in the brushwork. It’s also worth noting that he designed a special building with carefully controlled lighting to give people a very specific experience of seeing his paintings.
Because graffiti is illegal it usually has to be quick and dirty—as opposed to elaborately carved couples in flagrante delicto which would be long and dirty–or at least quick, so there’s not a lot of time for decorating, but I always appreciate it when it adds a little something to an otherwise bland space.
