Dear sundial friends!
Where is true North? This is a question interesting to gnomonists who intend to build a well working sundial.
Today I have inserted a really interesting article of Carl Niemann into my Machu Picchu - Link:
Über die Ausrichtung
prähistorischer Stätten
nach dem Teotihuacan - Norden

You can open this PDF- article easily from my Machu-Picchu-Link!
Good wishes!
