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

2016-11-24 Thread Darek Oczki
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).

first sundials

2000-09-26 Thread Al Schoepp

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.

 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.

Listed publishers are:
(US) Dover Publications, 180 Varick Street, New York, NY  10014
(Canada) General Publishing Co, 30 Lesmill road, Don Mills, Toronto, Ontario
