Re: First sundials
I've read that there's evidence that the first accurate & precise timetelling sundials were in China. Stone disks, marked like equatorial sundials, with a hole in the center that could be for a gnomon were found in China, dating to a time that's earlier than other sundials that have beenfound. Equatorial disk sundials supported by the disk and by the end of the gnomon on the ground are still in use.

First sundials
Dear all I would like to ask your opinion on the first sundials which inspired gnomonic inventions developed through following centuries. In all literature available in my country it is repeated that the first dials were sticks set upright on sent or big trees and rocks casting shadow on earth. This allowed the first men to observe the shadow motions throughout the day. Well, I guess it is a way to describe the beggining.. yet it does not satisfy me - sounds pretty boring :)Considering the scaphe and other hemispheric dials of Greece there seems to be a vast gap between the above concept and those very sophisticated dials. Does any of the group members have any other perspective on how it all could really begin? (apart from any alien intervention theory). -- Best regards Darek Oczki 52N 21E Warsaw, Poland GNOMONIKA.pl Sundials in Poland gnomonika.pl --- https://lists.uni-koeln.de/mailman/listinfo/sundial
first sundials
Hi, I thought some of you might be interested in seeing my first sundial. It isn't finished yet, still need to install the gnomon and it's probably getting too late in the year now to set it up outside. Hopefully as I learn I will get better results. www.telusplanet.net/public/a_schoep/shop/casting_results_projects/casting.htm -- Al
Re: first sundials
A basic question (I have not found an faq for this group). Can you recommend a book or books for someone wanting to make his first sundial? Another good book for beginners which has detailed descriptions on how to make several basic types of sundials (including complete materials lists with templates for various latitudes) and requires no special tools or knowledge is: Easy to Make Wooden Sundials by Milton Stoneman ISBN 0-486-24141-6 I picked up my copy for only $3 at the Adler Planetarium Bookstore in Chicago.
