In an old inventory, dated 1819, is this entry:--"Half-length
portrait of the King of Poland, purple velvet coat, etc., painted
by Lampi, member of the Academy of Vienna. Bought of Colnaghi for
£21."
Stanislaus-Augustus Poniatowski was proclaimed King of Poland on
the 7th of September, 1764, having owed his election to his lover
the Empress Catherine. It was during his reign that the infamous
partition of Poland was perpetrated, to which he lent a passive
assistance. He died in 1798.
