16th century

Gilt brass. Unsigned and undated.

The globe is set up with the hour-ring in the plane of the equator and the 6-6 diameter in the plane of the meridian. As the sun shines on the globe one half is always in the shadow, and the edge of the shadow as it moves round the hour-ring gives the time.

If the globe is turned on its axis so that the 12-12 diameter is in the meridian the shadow of the style at noon gives the sun's declination.

[G. 562]
