Those who fought for knowledge, incubation.
The greatest part of history within incubation is not only found in Ancient Egypt and her roots, it's those millenniums kept secret. There was Aristotle who pondered artificial incubation from stories he has heard, later wrote within his book IV. It wasn't until a French scientist continued to be foolish for knowledge, spared from death and hungry for knowledge, he is the one who changed history for mankind, knowing there was more to his discoveries. There is more to the mud incubators of Ancient Egypt than you may know.
