Isaac Kremer/ September 9, 2018/ / 0 comments
An instrument for determining the hour of the day by means of the shadow cast on a graduated surface. In its simples form, the non-portable dial consists of an iron rod fixed in a wall, its shadow moving over a series of radiating lines painted or cut on the masonry below. 2. Any similar graduated surface, especially when circular; as the face of a clock or meter. (Sturgis, 1900)
