Just over a month ago, on 1st December 2021, MacDougall Arts, of St. James's Square, held one of their regular sales of Russian works of art. Included in the auction was a portrait of Catherine II, Empress of all the Russias, otherwise Catherine the Great, by Dmitry Levitsky (1735-1822), together with a letter from Catherine to Count Piotr Aleksandrovich Rumiantsev outlining her inoculation strategy against smallpox. (The two items together sold for £951,000, if that’s of any interest.) This sale was the impetus or trigger for a talk I gave to the Blake Society AGM (19 January 2022). The title I gave it : “Inoculation should be common Everywhere”, derives from this letter by Catherine the Great.
