Short answers, pulled from the story.
John Everett Millais, Dante Gabriel Rossetti, and William Holman Hunt founded the Pre-Raphaelite Brotherhood in the winter of 1848. They formed a seven-member collective that included painters, a sculptor, and a critic to challenge the Royal Academy of Arts.
The Pre-Raphaelite Brotherhood used a method of painting in thin glazes of pigment over a wet white ground. This technique ensured that the colors retained their brilliance and stood in stark contrast to the muddy darkness produced by earlier British artists.
The Pre-Raphaelite Brotherhood faced public controversy in the year 1850 when John Everett Millais exhibited Christ in the House of His Parents at the Royal Academy. Critics including Charles Dickens condemned the work as blasphemous and ugly.
Elizabeth Siddal was the central muse for Dante Gabriel Rossetti in the Pre-Raphaelite Brotherhood. She was a model and poet whose relationship with Rossetti ended with her death from an overdose of laudanum.
The original Pre-Raphaelite Brotherhood effectively dissolved by 1853 after James Collinson resigned from the group. Only Holman Hunt remained true to the stated aims of the movement while the other members divided into factions.
