I WILL BEGIN WITH DIMENSIONS. As one should. I had a mathematician friend tell me once, perhaps twice, that dimension is concerned with the constituent structure of all space and its relation to time. I did not understand this statement and still I do not, in spite of its undeniable, obvious poetic charm. He also tried to tell me that the dimensions of an object are independent of the space in which that object is embedded. It’s not clear to me that even he understood what he was saying, though he seemed quite taken with the idea. What I do understand is that my canvas is twelve feet high and twenty-one feet and three inches across. I cannot explain the three inches, but can say that they are crucial to the work. It is nailed to a wall that is twenty feet tall and thirty-five feet across. The opposite wall is the same and the adjacent walls are but fifteen feet wide. And so the square footage of the space is five hundred twenty-five. The volume of the building space is ten thousand five hundred cubic feet. I am six feet tall and weigh one hundred and ninety-two pounds. I cannot explain the two pounds. I prefer that numbers be written out as words.
