Ancient coin collecting is an awesome hobby! I have one that scholars think was made by / designed by Pythagoras himself. For a few hundred bucks!
Recently I learned that only 3% of Latin works from 1450-1700 (including renaissance and scientific revolution) have been translated. Secondrenaissance.ai
Latin isn't terribly hard to learn, and it is surprisingly easy to read "technical" documents in Latin; because once you learn the terms the other parts are relatively basic.
Declensions seem very extensive and unintuitive to learn, like they had a completely different structure than modern languages (verbs adjective noun articles)
