1) During the long reign of Queen Victoria artists reacted differently to the new world shaped by the Industrial Revolution.
2) In particular, some grew/were (?) dissatisfied with Victorian materialism and found inspiration for their works in the past, particularly in medieval Italian paintings.
3) These artists used a techinique similar to that used by painters who worked before Raphael, the great Italian artist.
4) For this reason, this movement, which was formed in 1848, was called the Pre-Raphaelites. They depicted objects in a very clear way and every object and person was chosen for its (?) symbolic meaning, as in the Middle Ages.
5) They wanted to convey a moral message through their works. The painter turned into a sort of priest, though his works often had a sensual connotation.
6) The Pre-Raphaelites paved the way for the Aesthetic Movement of the 1870s.
