History, Sites and Products
A brief history of Sundials, some useful sites and sundials to make and buy.
Sunrise, Noon, Sunset; just by seeing the sun in it's various guises, our ancestors would have gone about their business, confident enough to be able to get back to their caves in time for tea.
Then progress came and shadow casting instruments called gnomons were used (that's a stick to me and you) to make primitive sundials. By 1500BC, clever Egyptians were using markings with the gnomon. With this improved accuracy, it was possible to "syncronise sundials" for important business meetings and liasons.
More advances were made and sophisticated weathy Romans carried small pocket sundials. There were also vertical wall mounted sundials on many public buildings.
During the Renaissance there were yet more advances and sundials became more sophisticated, incorporating calendars. They even showed minutes and some even had tide tables! However, by the 16th century, clocks began to supersede sundials.
But it is interesting to note that the French railway regulated its trains by sundials until the end of the 19th century!
Nowadays we don't need to rely on sundials as we have moved on a bit. But there are still plenty of sundials around and they are great for garden ornaments and for public sculptures.
For those of you hungry for more information on the history and development of sundials, Helen Lee of the Simon Frazier University in California has written a detailed online account.
NASA offers a simple explanation of how sundials work using animations and interactive graphics and gives detailed information on how to build a sundial yourself. The National Maritime Museum also has instructions and a printable template for making your own sundial. You can find a more academic approach to how sundials work at plus.maths.org in their article Analemmatic sundials: How to build one and why they work . After you have digested that, you might feel confident enough to visit Jurgen Giesens Physics and Astronomy site to view his analemma sundial applet which allows you to make your own analemma sundial, plus there are also pages on how to make a pie sundial and a horizontal sundial . For schoolchildren, I would recommend the Liverpool Museum website and their section Sunbeams and Sundials . Educators might like to have a look at this lesson plan for making a sundial, or, if you would like to make a simple paper sundial with your children, you could print out the templates and instructions at the BBC website.
Australian con trick!
In reading the literature you will find out that sundials are quite complex to set up correctly. Each one must be calibrated for the exact location it is in. This is quite important when buying one. My sister recently bought a cheap sundial and it took her a long while to find out that it was calibrated for Australia! On that side of the globe the numbers need to go the other way round. I leave you to work out why, took me long enough! But quite apart from that major issue, even two sundials in the same street as each other will have to be calibrated very slightly differently to catch the sun right.

SUNCLOCKS - (Human Sundials, using YOUR OWN SHADOW to tell correct time)!
If you are looking for a really unusual sundial, which is 'interactive' as well as being theft and vandal-proof - then a 'Sunclock' could be an ideal feature, and can be made by using almost any materials of your own choice. These use a person's own shadow to tell CORRECT clock time - even changing automatically without needing to be put forward/back, in Spring or Autumn. It can be set into hard or soft landscaping, and (if on grass) you can run a lawnmower right over it without any damage. As well as private gardens, parks, etc - they are very popular as a 'playground feature', for Schools.
So that you can create your own UNIQUE layout, Sunclocks provide a customized set of 'Sunclock' plans (containing all measurements and instructions) - which are created for the specific Latitude and Longitude, of your own location. The plans can be supplied as a printed booklet, or by E-mail (PDF format). 'Layout Plans' cost a maximum of £25 (various discounts are also available).
For more information and photographs, go to www.sunclocks.com.
