Definition
Relating to or characteristic of a dioptra, the ancient surveying instrument, or relating to its optical principles and surveying methods.
Etymology
From Greek 'dioptra' plus the English adjectival suffix '-al' (relating to), forming an adjective describing properties of the ancient instrument.
Kelly Says
The term 'dioptral engineering' shows up in ancient history texts and refers to the sophisticated mathematics used by Greek engineers—they could build straight aqueducts across mountainous terrain using just this one instrument.
