Terrestrial clockwork globe
Terrestrial clockwork globe. Geographical details on the sphere show California drawn as a peninsula. The Great Wall of China is depicted. In South America, there are two labels. New Guinea is still a part of the hypothetical southern continent, which is labelled. There are decorative ships and monsters. Part of the gore is missing in North Africa and the tropics and parallels have been redrawn in manuscript; 12 oceans are named.
A globe of this rank was published by Pieter van den Keere in 1613 but the 'Strait of Ie Maire' has been added to the present copy. No other copies of this rank are known to date. It is appropriate that the Janssonius gores of 1620 should be combined with a mid-17th-century watch movement but this globe was probably assembled during the late 19th, or early 20th century. If so, then care was certainly taken to disguise the fact that the work was done so recently.
The figure carrying the globe shows more of a similarity to the iconography of Christ on the cross than to Atlas or Hercules and may possibly have belonged to a 19th-century crucifix. The clockwork mechansim allows the globe to revolve at mean solar time about its polar axis, driven from within by a movement.
