David Rizzio, 1888 (w/c with gum arabic, heightened with white over pencil on paper)

Davide Rizzio, sometimes written as Davide Riccio or Davide Rizzo (c. 1533 – 9 March 1566), was an Italian courtier, born close to Turin, a descendant of an ancient and noble family still living in Piedmont, the Riccio Counts de San Paolo et Solbrito, who rose to become the private secretary of Mary, Queen of Scots. Mary's husband, Lord Darnley, is said to have been jealous of their friendship, because of rumours that he had made Mary pregnant, and joined in a conspiracy of Protestant nobles, led by Patrick Ruthven, 3rd Lord Ruthven, to murder him. The murder was the catalyst for the downfall of Darnley and had serious consequences for Mary's subsequent career.
