William Michael Rossetti in the context of "Shelley Society"

The Pre-Raphaelite Brotherhood (PRB), later known as the Pre-Raphaelites, was a group of English painters, poets, and art critics, founded in 1848 by William Holman Hunt, John Everett Millais, Dante Gabriel Rossetti, William Michael Rossetti, James Collinson, Frederic George Stephens and Thomas Woolner who formed a seven-member "Brotherhood" partly modelled on the Nazarene movement. The Brotherhood was only ever a loose association and their principles were shared by other artists and poets of the time, including Algernon Charles Swinburne, William Morris, Ford Madox Brown, Arthur Hughes and Marie Spartali Stillman. Later followers of the principles of the Brotherhood included Edward Burne-Jones and John William Waterhouse.

The group sought a return to the abundant detail, intense colours and complex compositions of Quattrocento Italian art. They rejected what they regarded as the mechanistic approach first adopted by Mannerist artists who succeeded Raphael and Michelangelo. The Brotherhood believed the Classical poses and elegant compositions of Raphael in particular had been a corrupting influence on the academic teaching of art, hence the name "Pre-Raphaelite". In particular, the group objected to the influence of Sir Joshua Reynolds, founder of the English Royal Academy of Arts, whom they called "Sir Sloshua". To the Pre-Raphaelites, according to William Michael Rossetti, "sloshy" meant "anything lax or scamped in the process of painting ... and hence ... any thing or person of a commonplace or conventional kind". The group associated their work with John Ruskin, an English critic whose influences were driven by his religious background. Christian themes were abundant.

William Blake (28 November 1757 – 12 August 1827) was an English poet, painter, and printmaker. Largely unrecognised during his life, Blake has become a seminal figure in the history of the poetry and visual art of the Romantic Age. What he called his "prophetic works" were said by 20th-century critic Northrop Frye to form "what is in proportion to its merits the least read body of poetry in the English language". While he lived in London his entire life, except for three years spent in Felpham, he produced a diverse and symbolically rich collection of works, which embraced the imagination as "the body of God", or "human existence itself".

Although Blake was considered mad by contemporaries for his idiosyncratic views, he came to be highly regarded by later critics and readers for his expressiveness and creativity, and for the philosophical and mystical undercurrents within his work. His paintings and poetry have been characterised as part of the Romantic movement and as "Pre-Romantic". A theist who preferred his own Marcionite style of theology, he was hostile to the Church of England (indeed, to almost all forms of organised religion), and was influenced by the ideals and ambitions of the French and American Revolutions. Although later he rejected many of these political beliefs, he maintained an amicable relationship with the political activist Thomas Paine; he was also influenced by thinkers such as Emanuel Swedenborg. Despite these known influences, the singularity of Blake's work makes him difficult to classify. The 19th-century scholar William Michael Rossetti characterised him as a "glorious luminary", and "a man not forestalled by predecessors, nor to be classed with contemporaries, nor to be replaced by known or readily surmisable successors".
