I’ve seen other work that suggested the possibility of focused light on Roman ships was feasible at the time. The real problem with this is the Greek Fire part. It’s certainly possible that Archimedes used the stuff, or flaming arrows, etc. to attack the fleet. But no one knows how Greek Fire worked, either.
That’s true. Whatever the formula was, it was lost during the Middle Ages. Its last known use was by the Byzantines against the Saracens.
Cool!
Ultimately, the point is, the Romans took the city, and Archimedes got chopped. :’)
I think the Archimedean screw was probably attributed to him, but antedates him by some years. The Egyptians didn’t invent it, apparently, they used (in ancient times, and still do) the shadoof (sp?).
I thought the Egyptians used the same type of device/technology to raise the Pyramids. One look and you can see how screwed up they are. Shadouf, shadouf, bod-da-da bod-da-da, shadouf, shadouf

I hate to dispute myth busters, but if the mirror is concave, much like the mirrors used in reflector telescopes, you could set quite a few things on fire and I wouldn’t want to stand in the focus. Bronze mirrors would probably not work, but real mirrors would. At the very least a blinding light could temporarily disorient sailors of opposing ships.
A couple of years ago I watched an episode of Mythbusters where they "proved" that you cannot split one arrow with another arrow.
The next day, I watched a show on the History Channel where an expert archer did exactly what Mythbusters claimed could not be done.
The Mythbusters' biggest issue with the "death ray," as I recall, was actually persuading enemy vessels to sit still long enough to do any real damage. They could scorch the wood, but not set it on fire.
Well, first of all, they were investigating the myth that Robin Hood (or his non-fictional, 12th-century equivalent) could have split an arrow. So off the bat they were limited to the kinds of arrows a medieval archer would have on hand. They acknowledged that you could split arrows made of bamboo or composite materials, if I remember right. But of course Robin wouldn't have had those materials on hand: his arrows were made of wood.
The biggest problem they discovered with wooden arrows was that they tend to split along the grain, so if it isn't parallel to the length of the arrow, then the arrow doing the splitting won't make it all the way up the length of the shaft. I would assume from that, that an arrow with just the right grain could be split.
I was actually surprised that they didn't give a verdict of "plausible" for this myth (under the right conditions, however improbable).
A Shadoof system might have delivered the volume, but the whole structure would have looked like a building site, cranes and workers instead of vegetation. Whereas a waterscrew system would have been visually non-obtrusive, and the workers could have been hidden below ground.
Thanks Oztrich Boy.
Should have guessed you’d be light years ahead of me.
It ain't "harmless" if you put somebody's eye out with that thing!
Wonder how well it would work with plastic sabots & a load of BBs?
Hmmmm...a 6' length of 2" pipe....
Strange that it wasn’t until AFTER 1492 that someone came up with the Spud Gun.

Now you know my dirty little secret: I’ve been growing ammunition; not food.
