Hello Gianni, I conclude that your analysis is correct for the early dial (1334). See attached note. The 1334 lines are correct for an orthogonal gnomon. The later dial (1346) has the correct lines for a polar gnomon. Whether it had a polar gnomon before one was put on in 1985 remains inconclusive.
I will send you the scanned document that Reinhold Kriegler sent me with pictures of the four sundials on the church. Regards, Roger From: Gianni Ferrari Sent: Thursday, August 28, 2008 3:46 PM To: LISTA INGLESE Subject: Re: equal and unequal hours Braunschweig Cathedral sundial again - 2 I am afraid but, perhaps, I have not understood anything! :-( Mario Arnaldi has written me that the Brunswick sundial on which time ago I have written a "Note" is one of the two ancient clocks of the cathedral, BUT IT IS NOT that on which we are speaking in these Emails. This clock ( of ours Emails) is on the contrary the second one, built few decades later. Since Frans affirms that the sundials were built in 1334 and in 1356 this means that the sundial of which we are speaking is that built in 1356. But I believed that my "Note" concerned just a sundial built around 1350 ! Questions: in which labyrinth I lose my way? who helps me to go out? And, most important, does someone have the images (good photos) of these mysterious clocks? I ask you to excuse me if also I have much contributed to entangle the things: - ( Best wishes Gianni Ferrari -------------------------------------------------------------------------------- --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
