The oldest documented description of hare coursing is the work known in English as "On Coursing". It was written by Arrian a Greek historian of the Roman period, circa 180 AD and is known in Ancient Greek as "Kynegetikos" and in Latin as "Cynegeticus". Arrian felt compelled to describe the sight hunt and sighthounds because the Ancient Greeks only knew the scent hunt; "On Coursing" complements Xenophon's classic work on that subject, "Cynegeticus" ("On Hunting"). William Dansey, an English clergyman, translated "On Coursing" in 1831.
