A gnomon is something that stands in the middle of a sundial instead of a person and you can use different types of gnomons because it does not matter of the height of someone so you can use different heights and types.
On our sundial the Gnomon is the person who is standing on it, but on other sundials it could also be a pole or something like a pole. The Gnomon is used like a clock hand and it points to the time on the sundial.
