_Abraham Raguineau_ (Dutch: 1623-1681).
This painter, born in London, settled at the Hague, where he
seems to have met with little prosperity. At a later time, he
was living at Leyden, and was writing-master to the Prince of
Orange.
The picture is signed, and dated (1657), at the top of the oval on the
left, and is the only known signed work of the painter in existence.
It shows us a pleasant-looking, if somewhat characterless youth, aged
18 (as the description states), whose coat, shirt, and collar make a
delicate study in cool grey tones.
