title: The Hippocratic treatise peri opsios (de Videndi Acie, On the organ of sight).
abstract: The nature and affiliations of the work are addressed. The closest affinities in medical subject matter (details of eye flux and cautery), linguistic expression (features of syntax, grammar and vocabulary) and stylistic tone (didactic and magisterial aspects) are seen to be with Places in Man. The inference that the work has an 'early' date and west Greek provenance, and that the author may have interacted with Alcmaeon or Empedocles, both known to have taken an interest in the eye, is examined. Evidence for an 'Egyptian' or 'Libyan' (North African) connection is adduced, and a case made for input from Cyrene.
