In the narrowest sense of the word, it consists of a flat plate (the dial) and a gnomon, which casts a shadow onto the dial. As the Sun appears to move across the sky, the shadow aligns with different hour-lines, which are marked on the dial to indicate the time of day.

Designing sundials has a long history in Iran. In an astronomical book entitled Zij-e Shahriyar ("Astronomical tables of the King"), composed in pre-Islamic Iran possibly in 555 C.E., there was a chapter on a method for graduating sundials.
