Ancient Sundials

‹ Ancient Sundials

Dialface ID 231

Abstract

A trace of gnomon hole is preserved along the broken right edge which coincides with the meridian of the dial. No metal remains. Three fragments have been joined to form the left half of a sundial. The equinox crosses and extends a little beyond the six preserved hour lines. Winter and summer solstice curves have been approximated by straight lines. The meridian extends beyond both solstices the length of the diameter of the inner circle.
