I think these are the most important sets of diagonal lines. One thing that I noticed that is interesting is that Cezanne often broke the front edge of the table. What I mean is that the small pieces of front table edge that you can see don't make one line but several different "table front edges". So, in my view that line is less important to the geometry of the picture, but the diagonal that represents the side of the table is very important - you can see this by the number of times it is repeated through the painting. If you look at it for a while you can see how neatly the painting fits the geometry. The right front corner (covered with drapery) is a particularly striking area. If you think about the necker cube and its reversals you can see how the space unfolds. (-> #4)
