Dear All, One of my colleagues recently took some photographs of a couple of items of gnomonic interest in Hamilton, New Zealand. These can be seen at:
http://www.cus.cam.ac.uk/~ph10/hamsun.html You can click on the thumbnails to make them bigger. Object one is a car-park-sized sundial with constant declination lines for the first day of each month, and analemmas for six or seven hours (apparently set for New Zealand time since there is nothing central for local noon). The concentric circles seem to have no obvious purpose other than ornamentation. Object two is curious. Can anyone identify it? It is in poor condition and some components appear to be missing. The photographs were also taken in pouring rain! It might be the remains of a heliochronometer but there are no obvious markings and no plaque to say what it is or how to use it. The mount can adjusted for altitude and azimuth. Suggestions welcome! Frank King Cambridge, U.K. -
