Dear Anselmo and all, > You can see one of these conical gnomon sundials in the web page of the > city of Gent in Belgium. This is a clever and elegant design, and very > easy to put into practice.
I assume you mean the sundial park in Genk (some 130 km east of Gent). The Genk site can be found at: http://www.biol.rug.nl/maes/genk/welcome-e.htm and the conical dial of Javier Bores is nr. 9. (Sorry, still no English text ;-) > Another of its virtues is that these dials are more robust, ie., > VANDALS-PROOF, than ordinary ones. This is a property which, at least here > in Spain, is an essential one (!). The weak point here are the steel cables used to keep the edge of the cone in a conical shape. These have to be repaired quite often, I believe. > I know there are more dials with that > kind of 'robusness' (for instance, several polyhedrons laid so that one > casts its shadow over the other), but does anybody know about some more > dials like these? For instance its neighbor, #10. Regards, Frans Dr. Frans W. Maes Dept. of Animal Physiology University of Groningen P.O.
