Well, Leonardo Da Vinci designed helicopters and balloons and all manner of contraptions ahead of his time, but he's not exactly ancient.
I think we will learn a lot more about ancient Greek civilisation during next year (Athens Olympic year with all the PR opportunities that accompany
that) but that won't help with your assignment.
Enjoy your time at ATS.
