With its three legs it can also be Martian.
I like the metal texture really!

thanks ... took a bit of tweeking to get the effect I wanted (slightly 
tarnished brass).

texture {
     gradient x+y
     scale 1.6
     turbulence 1
       texture_map {
         [0.0 T_Brass_1A normal {spotted 0.25 scale 0.04}]
         [0.5 T_Brass_2C normal {gradient x+y 0.5 scale 1.6 turbulence 
0.01}]
         [1.0 T_Brass_1A normal {spotted 0.25 scale 0.04}]
         }
     }

  Jeez, I haven't even done the 'spotted' or 'gradient' thing yet, but yes, 
I'll have a go now.

   Thanks for the inspiration.

     Nice image Jim.

Am I the only one who doesn't know what it is?

LOL! Well, I sorta knew of this mainly by illustrations from a few hundred 
years ago showing it. Idea is for steam to be produced from a fire 
underneath and make the upper part spin. Until now, after checking for info 
about it, I didn't realize it was basically reinvented from such an earlier 
time as 270 B.C. by someone in Egypt. Not sure why Paolo said "ancient Greek 
technology", although it has apparently been duplicated since that time.

As to the good rendering shown here, I didn't expect to see the wheel on the 
side because I only knew of the device as being just a scientific curiosity 
when it was created. That's how it usually gets described, that it wasn't of 
actual mechanical usefulness when it was first made and then the much more 
recent industrial age put steam to good use.

Hopefully a helpful suggestion: the brass texture might need an environment 
surrounding the model to prevent the typical suspended in space appearance.

Bob

I added the wheel because it's going in an scene .... the Aeolipile will 
power an elevator.
Like Bob said the device was never put to practical use ....
just thought it might be a cool adaption for my scene.

there is a bit of a floor there ... barely visable.
I was going for the object on a turtable, in a black box look for the QTVR 
stuff that I'm working on.
72 images looking down at the object, 72 images at the mid line, and 72 
images looking up from below the object.

Ciao

I was referring to Heron of Alexandria studies on this kind of tools,

I was referring to Heron of Alexandria studies on this kind of tools, and
the correct phrase would be "ancient Egyptian technology", sorry!
