Brass Cover Octagonal Sundial
This kind of sundial reached the height of its popularity during the 15th and 16th centuries. These mass-produced designs were not only more affordable, they offered simple operation, unlike more sophisticated astronomical instruments such as the astrolabe. Sundial of this age consisted of two boards, usually of wood, joined by a hinge, so that when open one is vertically and at an angle of 90° to each other. The inclusion of a compass allows for easy computation and joins together the two quadrants to respective tables, forming a horizontal and a vertical sundial respectively.
This octagonal sundial model was inspired by Charles Bloud of Dieppe, one of the most recognized gnomonists of the time, in France. Inside is a horizontal sundial and on its vertical board, there is a lunar volvelle, which can denote the time by the shadow cast by the full moon. On the top cover, there is an equatorial sundial type.
It is handmade in Spain and is polished with natural waxes. It also includes a booklet on its history and usage instructions.
