An Armillary Dial

This short piece features a 1928 photograph of novelist Edgar Wallace with a rather fine armillary sphere in his garden. It questions whether this dial, or one of the same design with an unusual bell-and-sphere supporter, dating from 1730 at Hever Castle, are unique or part of a production series from such an early date.

The Spherical Sundial

This article discusses various forms of spherical sundials, from simple painted stone spheres to the ancient concave hemisphere (Scaphe or Hemicycle) and the later, less effective, convex hemisphere. It also explores the projection of spherical coordinates onto a plane, linking them to the discovery of the analemmatic dial.
