In the 20th century artistic ideals changed, and art moved away from representing reality. After the First World War, Pre-Raphaelite art was devalued for its literary qualities and was scorned by critics as sentimental and concocted "artistic bric-a-brac". In the 1960s there was a major revival of Pre-Raphaelitism. Exhibitions and catalogues of works, culminating in a 1984 exhibition in London's Tate Gallery, re-established a canon of Pre-Raphaelite work. Among many other exhibitions, there was another large show at Tate Britain in 2012–13.
