Only one case of an unfinished ancient sundial can be found in the scientific
literature. Found on the Greek island of Delos, it was first reported in 1938,
although the sundial was then later considered lost. In our campaign of
October 2012, we rediscovered the sundial. Using new and elaborate techniques,
we created a 3D model of the sundial, which has enabled us to answer questions
concerning its construction principles and the manufacturing processes used.
Our first evaluation has revealed that, initially, its creators had intended
to construct a cut conical sundial. Its discovery next to a workshop suggests
that the sundial was left there in its unfinished state on the destruction of
the island’s main town.
