I typically work rather intuitively, asking my Guardian Angel please help, to determine the composition of my paintings.
In the case of my Apocalypse Triptych there were several problems from the outset, mainly sizes and the deadline. And choosing which subject I could reasonably approach in the time frame. This meant trying to understand, or surrender to the mysteries of the Apocalypse as they relate to the Medieval poetic vocabulary.
Gloria Thomas detailed the elements required for this work:
Balance
Proportion
Brevity
Clarity
Simplicity
Fidelity
Beauty
I could not afford to buy any new canvas or stretchers, but I had 3 old paintings 36"X36" and two 36"X18". I needed to paint these over and for them to be dry enough to work over top of. These fortunately fit the size limit, which was 36" on any side.
I had to decide how to incorporate linguistic metaphors, combined with analogy, to create 3 separate subjects from the Apocalypse. The intense problem for me was translating the Medieval devices into a "theater"-like setting on the vertical planes, especially of the 18"X36". For the three paintings to work as a triptych, the 36" sides would need to match--as opposed to going lengthwise out from either side of the middle square panel.
For whatever reason, my poor brain had a terrible time with wanting to go sideways ^

out instead of up-and-down, which seemed to destroy the symmetry of the triptych, but would have felt easier to tell the story. Three equal 36" squares would have been a lot easier for my mind to grasp in the time I had to complete the deadline. For instance, the late Medieval Angers Tapestry goes in reading sequence in my mind.
I am not even certain if ALL Medieval manuscript artists even knew how to read but I am 100% certain their minds were in the realm of Heaven. Thus, being able to communicate the lessons of the Holy Gospel to others who could not read letters, illustrating three levels of analogy at the same time, as a sort of play.
