Oh this is by no means limited to ancient times, try giving any two young children the same amount of food, but cut into different sized pieces - smaller cuts result in more pieces than the larger cuts... Guaranteed meltdown. :)

The simple solution- have one cut the food in half, but the other gets to choose their half first from the two.

That's a good time as any to learn that might makes right.
