Using the sundial is easy - you hang it up, edge-on to the sun, and check where the gnomon's shadow falls on the dial. In my laser-cut version, the inside of the dial is very dark, so the shadow doesn't show up very well.

Vertical sundials are designed to your exact longitude and latitude to ensure they perform as accurate time pieces. The dial plate has a gnomon, an object used to cast a shadow, and hour lines to indicate the passing of time.

Actually plotting the points washes out all those variations and gives a remarkably accurate sundial. Pick a site with good solar exposure - a true East-West wall is ideal, but small variations will still work. You just lose more morning or afternoon readings as …

Sundials resembling the kind of which Vitruvius speaks were in use in Egypt from at least 1200 B.C. These were vertical hanging sundials, semicircular in shape with a horizontal gnomon at the top and centre.

This unique piece tells the true solar time anywhere in the world using just the power of the sun, achieving surprising accuracy estimated by experts to be better than +/- 10 minutes. Once set up it is also a model of our planet with the bridge parallel to the earth's axis, so it can thus be used as a precise compass too.

Can be hung vertically using the keyholes; nails and screws not included. A great versatile decor for indoor or outdoor display but are not rust or weather resistant. This item ships fully assembled in one piece. This is a single copper colored wall sculptures. Rustic style.
