The contacts with India may have given the Romans some new ideas in science and technology.
Aelopile wasn't very practical. Others have pointed out that steam gimmicks were used.Are their any yet undiscovered or unmentioned inventions within the Roman Empire that you think we will find evidence of in the future?
Or maybe we will never find those evidence but it is still possible or likely that they had the knowledge of and used certain kinds of technology?
Examples:
- Practical applications of the Heron aelopile?
- telescope?
- windmill?
- compass?
- wheelbarrow?
- others, such as...
What about the safety pin? The ancient Greeks had something similar, but it was not quite there and eventually forgotten. It only needed a minor modification.
Note: The Aelophile, was an interesting steam construction by the Romans if it had been developed more, you could see steampunk Romans.
