Think about it, some guy in the 13th century was just improving what the ancient Greeks (like Hero of Alexandria) was doing in the first century - to me that is amazing. You gotta love those ancient Greeks though, their motto should be "Been there, done that."

I'll tell you what, how about you try to convince me that what you're saying is worthwhile by providing some sources that prove what you are claiming is true?

The crank and connecting rod mechanism was first used in Roman water mills of late antiquity. The early known evidence appears on a late 3rd century AD relief of a saw mill from Hierapolis, Roman Asia, in which the mechanism converted the rotary motion of the waterwheel into the linear movement of the saw blades.

It seem to me that if Hero of Alexandria (along with other ancient Greek and Roman inventors) hasn't piqued your curiousity already where you had to look them up on your own, it wouldn't matter what proof I provide - it won't really mean anything.

Your picks are your picks and they are important to you; and I am not trying to dismiss their achievements by mentioning the ancient Greeks. :(
