> Voltaire (1694-1778) wrote a satirical account of a medieval university's oral examination on medicine: the examiner asks why morphine puts people to sleep, and the student confidently replies that morphine has a "dormative essence".

It was Molière (<1622 - 1673), who wrote a play that featured an apothecary (explaining the functioning of opium to laymen), but no examinations.
