Man, I kind of think people chase the exact 'ancient wisdom' thing a little too literally sometimes. 'The Richest Man in Babylon' has that nice parable style, but honestly, a lot of its core ideas about saving and avoiding debt are pretty timeless. If you want that specific 'lessons from the past' feel, check out 'The Wealthy Barber' by David Chilton. It's not ancient, but it uses a similar storytelling approach with a barber giving financial advice—it hits that same 'wise elder passing down common sense' vibe in a modern setting.
For something that actually digs into historical economic thought, 'The Ascent of Money' by Niall Ferguson isn't a parable book, but it traces the history of money, credit, and banking from ancient times. It’s way more of a historical deep dive, but you'll see how old principles evolved. It made me realize how old the concept of compound interest really is, which is a big part of the Babylon book anyway. I ended up skimming some chapters, but the ancient bits stuck with me.
