Product Description

The gnomon is made from two brass plates with a narrow air gap. At solar noon, when the sun is directly over head, a line of light shines through the air gap for a few minutes only. This enables the sundial to be set absolutely accurately to true north, knowing only the time of solar noon at your exact location.

This handsome modern sundial is made to our design out of solid brass, and weighs 5.25 kg. It is 31.5 cm. wide, 14 cm. overall depth, and 13 cm. overall height. (This is equivalent to 11½lb, and 12.4 inches wide by 5.5 inches depth by 5.1 inches overall height).

The fixings are concealed to avoid pilferage. The base plate  is first aligned to true North and screwed down to a suitable plinth; the sundial is then attached to the base plate using the recessed screws which fit in to the mounting blocks.

The gnomon (which casts the shadow) is the "oxhead" in the centre of the dial. At 6 am, the shadow from the top of the gnomon just skims the top of the left hand "ear". By 6.45 the shadow has traversed the ear, and arrived on the main dial plate. It slowly moves across the dial. At noon, the sun is directly overhead, and the shadow is immediately below the gnomon in the centre of the dial plate.

The polar dial is supplied with a base plate which adjusts the angle of the gnomon for different latitudes as shown in the table. 

The hour lines on polar dials are parallel with the gnomon; they are indicated with Roman numerals for winter time and Arabic numerals for summer time. At 6 a.m. winter time the shadow of the oxhead gnomon just skims the left hand "ear" of the sundial, and from just before 7, the shadow has reached the left hand end of the main dialplate. At noontime, the shadow is directly under the gnomon, and at 6 p.m. it arrives at the top of the right hand "ear"
