Description
The horizontal dial is the most common form of sundial. The portable version proved very popular with the upper classes during the 19th Century. During this period it could best be described as the wristwatch of its day.

The hour lines are engraved onto a horizontal surface, with a gnomon (pointer) in the centre. Seasonal variations (caused by the earth’s orbit being elliptical, not circular) have to be compensated for, as they can effect the raw reading by up to 18 minutes.
