That mural again, again
Monday, November 12th, 2007The new Edward Said mural (dedicated last week: for earlier posts see ‘What would Edward Said have said?’ and ‘That mural again’) is, to be fair, no uglier than the other murals decorating the Cesar Chavez Student Center at San Francisco State University. You can read all about them here on the Student Center website.
A little detail of the Malcolm X mural caught my eye. To quote the Student Center’s description: ‘An image of the continent of Africa engulfing the United States is shown in between the images of Malcolm, and is based on the Mercator projection, which conveyed the relative size of Africa compared to the U.S.’ This is bizarrely wrong. Leaving aside the question of what exactly pointing out that Africa is bigger than the United States is supposed to prove, the muralists seem to have their cartography confused.
The world map on the mural does not use the Mercator projection. If it did, the effect would be precisely the opposite of that claimed: America would be made to appear disproportionately large compared to Africa, as Mercator maps distort land area so that the further you get from the equator the larger places appear. The map on the mural appears to use the Peters projection, which sought to overcome this distortion, and, supposedly, also serve the cause of global social justice by removing the Mercator map’s supposed bias towards the rich North American and Eurasian countries. In the mural, however, this projection is used with one significant alteration: Africa is grossly distorted to appear much larger than it ought to be, even by the standards of the Peters version. The United States, by contrast, is left at its (relatively smaller) correct size. The three images below show the results clearly: from top to bottom, Mercator, Peters, Malcolm X mural.



So, in the name of correcting an alleged distortion that didn’t suit their ideological position the makers of the mural deliberately introduced another that does, while claiming that their distortion was not a distortion.
Edward Said is in good company here.
