I found that part confusing too, Sam. The best I can come up with after rewatching the video from page 72 and rereading the exercises on 73 and 74 is that you kinda just guess where the horizontal will be. Maybe its something that comes with more practice? He talks about the question of "what came first the square or the circle?" and how they're going by the idea that the circle came first. As to say in order to find a square in perspective you should draw an ellipse. But I dont see how thats any less valid than drawing the square first to determine the ellipse. Im going with just ignoring that part for now and defining the square first in hopes that it will make sense to me later :)
