Editing Gnomon (section)

===Vitruvius===
[[Marcus Vitruvius Pollio|Vitruvius]] mentions the gnomon as "{{lang|la|gnonomice}}" in the first sentence of chapter 3 in volume 1 of his book ''[[Vitruvius#De architectura|De Architectura]]''. That Latin term "{{lang|la|gnonomice}}" leaves room for interpretation. Despite its similarity to "{{lang|grc|γνωμονικός}}" (or its feminine form "{{lang|grc|γνωμονική}}"), it appears unlikely that Vitruvius refers to judgement on the one hand or to the design of sundials on the other. It appears to be more appropriate to assume that he refers to geometry, a science upon which gnomons rely heavily. In those days, calculations were carried out geometrically, in contrast to the algebraic methods in use today. Thus, it seems that he indirectly refers to mathematics and [[geodesy]].{{fact|date=August 2023}}
