The Posographe

Take a look at this amazing old device:

If anyone has any pointers to the mathematics of this kind of device, I'd love to know about it

I guess it would be quite feasible to work out how to make them eventually, but it looks like a lot of work to figure out.

Thanks for the link! Quite a device. It would be interesting to find a work that discusses what mathematical functions can be implemented with mechanical devices...
