Dear Roger, This is all good fun. You note...
> The underlying image of the sundial is clearly > for a 1755 sundial at 55°... If you zoom in on the pelican version you can see that the 55° turns into 53°. This squares with the latitude of Eyam which is 53°20'. On Patrick Powers's photograph the 53 does look like 55 but the "20 minutes" shows up clearly. All the best Frank --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
