Sundials and gnomons pointing out dates and times are a beautiful reminder ofhow we understand the movement of the Sun and use it to structure day and year.They also encapsulate the basic astronomical knowledge and concepts of theindividuals and therefore their societies which have built them. At the heartof every sundial lies the recognition that the daily and seasonal change oflight and shadow is repeated over and over again, in the past, present and intothe distant future. Such knowledge was developed well before any writtendocuments existed during times when observing did not mean measuring but ratherwatching and embracing the findings into a far deeper ritualistic religiousframe work. A 4,000 year old monolith located at Gardom's Edge with itsstriking orientation and in the midst of a landscape rich in other monuments ispresented as a possible example of such astronomical knowledge and how it mighthave been applied to create a deeper meaning for this monument.
