Happy to see the Fall of Civs podcast on HN. An amazingly well produced, thought provoking podcast - highly recommended by this Internet Stranger!
Carthage was the and only real sea power in the region and its funny yet sad that they labelled ship parts to make construction more efficient. The Romans eventually capatured a ship and were able to use the built-in guide to make their own copies. Rome used the ships to attack and defeat Carthage.
I often wonder what the world would be like if Rome fell and Carthage survived. Adding insult to injury even words like Africa are Roman terms that we use today to describe where Carthage existed.
