Well, lets just take the first one. Allegory of the outbreak of war. We see that the right hand side Mars the god of destruction (marked with blood stained sword and sheild) is taking the husband away to the underworld... death... war. and the grasped hands of the lovers And on the other side is Venus (in my opinion) is aiding the maden in her futile fight to keep the lovers together... also marked with the angels holding the lady.

Further, if you look to the lower right hand, there is a lady holding a lute. Well, it's broken. The Lute has symbolized harmony. Since it's broken - I feel that harmony can not exist with war.

That's just Rueben's Allegory of the Outbreak of War.

I have to go back to work - I'll write more later. But nice question. :) Anyone else want to do one?
