What can be said about Edouard Manet (23 January 1832 – 30 April 1883), once you have seen Olympia or Le déjeuner sur l'herbe. I daresay you cannot consider him a transitional figure, if you think he towers so above those who followed. Myself I would call him a Goya who blinked, but that may be too idiosyncratic a summary.
The Tate has one of his cats, "Woman with a Cat," which they call an "unfinished portrait ... of Manet's wife." Sigh.
