On my website now you can see an explanation of the sundial at the 'Prinsenhof' in Groningen (1731), the most beautifull sundial in the Netherlands. I redesigned the sundial in a more modern version. So it was possible to make things clear layer per layer.
The text is in Dutch but for sundial specialists the figures suffice.
