The tall rectangular structures, known as obelisks to the ancient
Egyptians, took advantage of the shadow-creating effect of the Sun.
The obelisks were pointed, and as the Sun moved across the sky, they
cast a large shadow upon the ground. The path of the shadow could be
mapped out with intervals that represented the hours of the day. The
Egyptians constructed these monuments with great care, often adorning
them with elaborate hieroglyphics. Their location was chosen to ensure
that the angle of the shadow was accurate. In addition, markings on
ancient obelisks indicate that the Egyptians made careful note of
the Winter and Summer solstice.
