Get a second opinion, in Pseudo-Aristotle's 'About the Secrets of Secrets'
Medium: Ink and pigments on vellum
Believed in the middle ages to be Aristotle?s letter to Alexander the Great, ?About the Secrets of Secrets? concerns government and is a Latin translation of an Arabic work. A London scribe and King's Clerk, Walter of Milemete, and a team of artists probably made this richly decorated copy in 1326-1327. Milemete intended it to accompany his own treatise on royal virtues for presentation to Edward III. The 'Secrets' was owned by the Earls of Leicester, at Holkham Hall in Norfolk, from the 17th to the 20th centuries.
The 'Secrets' includes a section on healthcare. Here 'Aristotle' advises the king to get a second opinion: "do not place your confidence in only one doctor." The illustration shows 'Aristotle' and the king before two physicians, who hold up specimens or medicine in green vials to examine them.
