This is F G Stephens. He was a friend of the artists Holman Hunt, John Everett Millais, Dante Gabriel Rossetti and Ford Madox Brown from their studies at the Royal Academy Schools. He modelled for many of their paintings and joined the Pre-Raphaelite Brotherhood in 1848. This portrait was made before the formation of the brotherhood and it is much more loosely painted than strictly Pre-Raphaelite works.Stephens later gave up painting to work as a critic and writer. His reviews helped to advance the cause of contemporary British art and were particularly favourable to his former Pre-Raphaelite colleagues.
