Illustrations of history

I think I can imagine how that works, but I'd really like to see it in action. Kinda clever, dem' Cambodian Folks. Ah, one more question, when was the Cambodian Medieval period? Ah here it is...

"The mediaeval history of Cambodia starts roughly in the 10th century, when the Khmer Empire had established its strong foothold in Cambodia, and ended in the 19th century, when Vietnamese attacks started happening in Cambodia." https://thebettercambodia.com/the-mediaeval-history-of-cambodia/

I'm glad to see that at least one other person also has trouble spelling medival, mediaval, midiaeval, or whatever.
