Not sure if you know Chinese or not but seal script will look rather familiar to anyone who knows Chinese:

https://en.wikipedia.org/wiki/Seal_script

If you look at the picture on the upper right, you can make out "tian xia" and "wang" -- all under heaven (i.e. the world) and king (the character for emperor isn't invented yet)

> the character for emperor isn't invented yet

Hmm it's right there。 The 4th “皇” and 5th “帝”。 And the combined form “皇帝” - a title invented by the First Emperor himself。

Good catch. But that just adds more to my point: modern Chinese can understand seal script to a large extend because seal script is the ancestor of the modern (non-simplified) Chinese. My guess is that neither you nor I are "Indiana Jones".
