Connection to Astronomy
What time it was? If the sun is up, you can figure it out. As the sun "moves" steadily across the sky, stationary objects cast corresponding shadows. As the shadows position changes, it can be used to indicate the time of day.
Throughout history, many different cultures used sundials to mark the passing of time. A sundial shows the time by displaying the position of a shadow on a flat surface, which has markings that correspond to hours. The "gnomen" is the part of the sundial that casts the shadow.
