Kratzer's 'strange' instrument in The Ambassadors is described in some detail in Peter Drinkwater's self-published 1993 booklet "The Sundials of Nicholas Kratzer". The item is shown disassembled and, as Drinkwater shows, is either faulty or inaccurately drawn. Regards, John ----------------------------------

Kratzer was a German mathematician, astronomer and instrument maker who worked as King Henry VIII's astrologer. He was a drinking friend of Holbein. Find his picture in the Wikepedia entry for Nicholas Kratzer. Holbein was probably using Kratzer's instruments in the Ambassador's picture, which was painted a few years later in 1533. Same shepherd's dial, same strange instrument, same polyhedral dial (but unfinished), same little dial-like thing with the spike and square hole on his table.

This huge painting, it's not far off 7ft square, is here in London at the National Gallery and it is now available to view under Google's Art Project at: http://www.googleartproject.com/museums/nationalgallery/the-ambassadors Painted in 1533 it has the most interesting collection of contemporary dialling equipment all of which are painted in immense detail. There are two globes (one terrestrial and one celestial), a quadrant, a torquetum, a polyhedral dial and a shepherd's dial and some others I don't know, all of which are set in such a way as to tell some 'story' to the understanding viewer. Until now it has been almost impossible for a sundial-interested visitor to the gallery to attempt to understand much of the detail - there just isn't time - but now with this view you can. You can even see for yourself the four place names marked on the terrestrial globe (one of which helped to identify one of the depicted persons as Jean de Dinteville, the Seigneur of Polisy) and you can even read the music and words in the open book and guess at the date and time shown on the shepherd's dial.. It doesn't (I think) help with viewing the anamorphic skull as a skull - or at least you still have to turn your monitor round to do so! - and I STILL don't understand the object behind the shepherd's dial... Anybody know what that might be?
