ancient inventions thread.
stuff that was invented in ancient times and then rediscovered or reinvented.
imma start:

greek flamethrowers:
An incendiary weapon consisting of a large syringe mounted on a pivoting turret. Much like a modern flame thrower, a flame mounted in front would ignite the incendiary chemical contained inside the syringe. Furthermore, the chemical consisted of a unique concoction, that not only carried a flame, but caused the flame to worsen as a reaction to water being applied, making it perfect for naval defense at the time.

as early as 7k BC, Northern Indians were using drills to make holes in teeth and remove decay, and were replacing lost teeth with artificial components such as ivory.

some form of passive eugenics was implemented in almost all ancient civilizations.
The Romans made it a civic duty for their aristocracy and upper class to have more children than the others.
The Greeks would put to death weak and infirm children.
The Persians implemented a caste system, similar to the indians, based not only on occupation but genetic heritage.
The Chinese for a time had a strict economic hierarchy and at times forbid certain marriages.
