The only source I can find online for the ancient Egyptian image in the upper left is this Reddit post. I don’t know how trustworthy the guy writing it is, but he apparently writes about ancient Egypt a lot. He explains what’s going on in the picture and includes some more ancient pictures of roach combat.
TLDR: Ancient Egyptians were afraid that roaches would eat their mummified bodies and therefore interfere with their afterlife.
