Diptych Sundials and Compasses
Portable sundials with built-in compasses were introduced in the 15th century and take many forms. Often they were made to look like books. When opened, a cord would be pulled tight to act as a gnomon. The compass would be used to align the sundial with north then the shadow of the cord would indicate the time.

This sundial is a replica of one made in Germany and dated 1643.
It is a single latitude dial (40 degrees) and its brass gnomon support is movable and fits into a small metal bush for use. The decoration of the floating compass card is particularly attractive. The case is made of beech .
METHOD OF USE
Position the gnomon support in the vertical position, then rotate the whole compass until the Lys flower on the floating compass (North) coincides with the number 12 of the quadrant. The thread casts a shadow which gives the sun´s time.

Shepherd Sundials
The shepherd's dial, also known as the pillar dial, traveller's dial or cylinder, was one of the simplest and most widely used portable sundials. It indicates the time of day from the sun's altitude, which also depends on the latitude and time of year. Consequently, each dial is designed for accuracy within a particular latitude and is adjustable to the correct date. The hours are marked in curves around the column.
Polyhedral Sundial Ref: LH-A214 The polyhedral sundial represents the pinnacle of the sundial designers art.
Its different sides are illuminated at different times as the sun moves, and the time can be read from the illuminated side that is most convenient.
This model is an accurate replica of the one manufactured by Stefano Buonsignori in the XVI century which is located in the Institute and Museum of Science in Florence. The sundial has eighteen hexagonal sides of which seventeen correspond to solar quadrants with different orientations and inclinations.
Price: £52.00 (Including VAT at 20%)
David Beringer's Quadrant Ref: LH-H26 This model is a reproduction of a mobile cubic quadrant that dates back to 1736, and is thought to be the invention of David Beringer of Hapsburg (Germany).
It is made up of an articulated arm, which allows us to incline the cube in a North-South direction, and a plumb line on the eastern side that moves along a graduated scale and can be used to adapt the instrument to the latitude of the measurer.
A delightful ornament and source of interest for anyone with an enquiring mind.

British Sundial Society
The British Sundial Society was formed in 1989 and is a thriving and friendly Society of some 500 members. Its objects are to advance the education of the public in the art and science of gnomonics and the knowledge of all types of sundial; to catalogue and advise on the restoration of sundials that still exist in the British Isles, and to research their history.
