Description
The Butterfield dial was named after the man who popularised this kind of sundial. His name was Michael Butterfield, and he was an instrument maker in Paris, though he originally came from England.
Butterfield dials are a type of horizontal dial, normally octagonal or oval in shape, and are quite small. They have several different hour scales marked out on them, each of which is used at a different latitude. However, the gnomon also needs to be adjusted for the latitude. Butterfield designed an elegant scale for the gnomon adjustment, in the form of a bird. The beak of the bird marked the place on the latitude scale of the gnomon, which was lifted up or down until it was at the correct latitude. A compass in the bottom of the dial was used to make sure that it was pointing in the right direction.
This kind of sundial was not very accurate, but they were made in very large numbers, so they were obviously very popular. Most of the existing ones came from France, where many different makers produced them.
