Hypatia Sundial

Manufacturer: Antiquus Brand: Obscuriosity

A horizontal sundial consists of one dial plate, marked off in hours, and the gnomon which sits on the noon line and projects out from the dial plate. In order to tell the correct local time, the gnomon must be parallel with the Earth's axis, or, in other words, that it should point towards the celestial pole. In the northern hemisphere, this means, for practical purposes, that the gnomon should point at the Pole Star. The chief advantages of the horizontal sundial are that it is easy to read, and the sun lights the face throughout the year. All the hour-lines intersect at the point where the gnomon's style crosses the horizontal plane. Since the style is aligned with the Earth's rotational axis, the style points true North and its angle with the horizontal equals the sundial's geographical latitude. Made of wood and brass, this historically accurate sundial, based off an original in the Naval Museum of Madrid, features a compass and beautifully printed sundial faces. The exterior cover is topped with a brass plate depicting the magnetic astrolabe of Athanasius Kircher. The perfect item for those with the spirit of discovery.

This octogonal model is based off a design by Charles Bloud of Dieppe in France. Inside there is a horizontal sundial, with a compass. On its vertical table, lunar volvelle for telling the time at night (more info below). The cover features an equatorial (or equinoctial) sundial. It comes in a beautiful case and has a booklet with history and instructions for use. Two options are available for the cover: one topped with a colored paper, the other an etched brass plate. How to use the lunar volvelle: The lunar volvelle converts the time as read off the sundial, cast by the shadow of the moon, and converts the reading the correct time (within an hour or so, these could not be as accurate as a sundial). Set the point on the volvelle to the current lunar age (1-29, with 1 being the new moon, and 15 being the full moon). The current solar time corresponds to the time indicated by the disc. In other words, the dial simply offsets the time to correspond with the precession of the moon. Historical Example: Bloud-type magnetic azimuth, diptych sundial ca. 1665

The polyhedral sundial represents the height of knowledge of gnomonics, the science of the sundial. Since it has different sides, these are not illuminated at the same time. As the sun moves, it illuminates the sides depending on the time of the day and this way it can be seen from different angles. This polyhedral sundial is a true replica of the one created by Stefano Buonsignori in the 16th 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. A compass in the top enables correct alignment.
