Dear Sasson,
I think the accuracy to plot the hour lines on a cylindrical surface is more
easy that a conical surface, but I not think that in the Roman era there was no
need

Thanks for your reply, Sara.
Although the dial in my previous message doesn't seem cylindrical, I can
assure to you that it is. See the attached side-view of the dial

Hi.
Greek and Roman sundials measured temporal time. They were generally spherical
or conical, and, if I understand correctly, their surface was designed to
provide a mirror image
It has eight vertical sundials with pin gnomons. The most famous Roman
sundial was likely the large horizontal azimuth dial in Rome which used an
Egyptian obelisk for a gnomon. Romans also used altitude dials, including the
pillar dial.

I think my question may not have been clear. What I am interested in finding
out is
1) Greek and roman sundials break up the day into 12 equal parts but the
amount of time that will pass between each part will not be equal
Does anyone know if the Greek and Roman sundials would in actuality show what
they are theoretically supposed to show in term of the unequal hours? The
gnomon was either horizontal or vertical, not on an angle.
Thanks,
