From Giles Deleuze, The Logic of Sensation, p.68:

We can thus summarize these laws of the triptych, whose necessity is grounded in the coexistence of the three panels: (1) the distinction between the three rhythms or the three rhythmic Figures; (2) the existence of an attendant-rhythm, along with the circulation of this attendant throughout the painting (visible attendant and rhythmic attendant); (3) the termination of an active rhythm and a passive rhythm, with all the variations that depend on the character chosen to represent the active rhythm.

Of course:

These laws have nothing to do with a conscious formula that would simply need to be applied; they are a part of this irrational logic, or this logic of sensation, that constitutes painting.

If it helps to read the book, read the book, otherwise, proceed.
