that he settled in Cos about b.c. 640 and imparted this and other 
astronomical knowledge to Thales of Miletus, who handed it on 
to Anaximander. 
The earliest recorded sun-dial (if indeed it was a dial) is that 
of Ahaz, about 700 b.c. (2 Kings, xx, 11; Isaiah, xxxviii, 8): 
“And Isaiah the prophet cried unto the Lord: and he brought 
the shadow ten degrees backward, by which it had gone down 
in the dial of Ahaz.” In connection with this it is noticeable 
that the Babylonians had great influence in Judsea during the reign 
of Ahaz. 
There are a good many Greek and Homan sun-dials preserved 
in museums in this and other countries, dating from as early as 
about 300 b.c. These dials were usually made by hollowing 
a hemispherical recess, or often half a hemisphere, in a block of 
stone, fixing a metal pointer terminating at the centre of the 
sphere, and tracing the hour-lines on the curved surface ; hut some 
other varieties have been discovered, and many more are mentioned
