Hi all,
I just receveid a message from Gigi Ghia ([email protected]), an italian
gnomonist, about this matter. I translate for him.
Gigi reports a website of Francis Ziegeltrum, where he shows a mechanic device
to reproduce the ‘8 curve’, as it is called by french gnomonists, obviously a
bit approximate.

The same author published an articol on Cadran Info n.29 (2014) of the french
gnomonic association.
ciao Fabio
