A colorful portrait of Pyotr Potemkin by Spanish painter Juan Carreño de Miranda is on display in Museo del Prado in Madrid.
During his envoy to France he introduced a new term, Avgardent (Авгардент), into the Russian diplomatic vocabulary.
He travelled to Vienna in 1674 to discuss common actions against Polish king John III Sobieski.
During his negotiations in Madrid he insisted that the King of Spain take off his hat every time Potemkin mentioned the title of Tsar of All Russias.
Potemkin insisted that the Danes bring a second bed into the chamber and conducted all the talks lying down, thus showing the equality between the countries.
