Georges Focus was a French engraver and painter who was born around 1639–1641 in Châteaudun and died on February 26 (or 27) 1708 in Paris.

Only eight pieces are known, including a series of six prints representing Roman landscapes, dedicated to Charles Le Brun and published by Girard Audran in 1678.

He seemed to take himself for the king of France or the Pope, believed to be persecuted by the Academy's members, or threatened by the Beast of Gâtinais, a famous feral wolf.

[2] These drawings might have been saved by close relatives of Focus, and they have been preserved until the 21st century because of their artistic quality[1] His contemporaries would probably have characterized Focus' mental state as "mania";[4] Bernard Granger, professor of psychiatry at René Descartes University, proposes, with all due caution, the retrospective diagnosis of schizo-affective disorder.

[6] An exhibition at the Palais des Beaux Arts in Paris, in 2018, allowed for a fresh look on the "written drawings" of this crazy artist from the seventeenth century.

[6] Focus' prints are landscapes in an Italian style close to that of Gaspard Dughet, Francisque Millet or Étienne Allegrain.
