The truth: we will never know.Actually, the current thinking is most of the workforce were skilled craftsmen, paid well for their hard work and ingenuity.
They paid them in grain, maybe millet, and beer, plus some gold.
The facts: they didn't eat pop-tarts, chex, fruity pebbles, fruit roll-ups, doritos, etc. basically all the garbage
we eat today.
Cereal used to mean what it actually is: rice, oats, barley, grains, etc. and it was prized.
