In 1981, Royal Academy of Arts in Britain held ‘A New Spirit in Painting’ exhibition which brought about the revival of a new representational painting. Afterward in Britain, a new representational painting developed in the name of New Spirit Painting after the title of the exhibition, and it also prospered in German, Italia, America, in its own ways. Because the New Spirit Painting artists in Britain haven’t worked in groups as the new representational painting artists in German and Italia do, they’re rather less known, but the world of British arts including Tate Gallery are illuminating Paula Rego(1935-), Stephen McKenna(1939-), Stephen Campbell(1951-), and so on as major artists. They create their works of symbol systems like riddles with the features which can be understood based on each individual’s ethnicity or experiences. Among them, Paula Rego from Portugal met British art while going to Slade School of Fine Art in London in 1952. She came back to Portugal in 1959, but went back to Britain in 1975 after her father’s property was confiscated under the portuguese dictatorship. And then since 1980s she came to attract people’s attention as an artist of new British representational painting, which is an artist of New Spirit Painting, was put up as a candidate for Turner Prize in 1989, and was appointed the first artist at the National Gallery in Britain and received a studio in 1990 for 1 year. In this way, she’s secured her position as a remarkable artist in Britain, but her works express her experiences in Portugal and display Portuguese sentiment rather than British one. Nevertheless, the fact that she’s been the center of attention as a New Spirit Painting artist in Britain tells us the characteristic of New Spirit Painting which attaches more importance to one’s personal experiences than on one’s nationality. Yet, New Spirit Painting also has the characteristic to express an individual’s experiences through one’s own symbol systems which makes it difficult to understand their meanings easily. In most of her works, her personal experiences are revealed through a symbol system, but 〈Girl and Dog〉 series are noteworthy as the pieces displaying the main characteristics of New Spirit Painting because they were created when she was under great mental stress and are estimated to be the most mysterious works. This paper focuses on these things through the series of 〈Girl and Dog〉 which have never been separately studied on. 〈Girl and Dog〉 series were produced in advance to the death(1988) of her coworker, her husband Victor Willing(1928-1988). In 1986, his multiple sclerosis took a turn for the worse, causing the symptom of paralysis of the limbs and he received the diagnosis that his remaining life would be short. Rego’s friend, Colette, suggested her that she do something meaningful before he died. So she created 17 pieces of 〈Girl and Dog〉 series from 1986 to 1987. This production background hints that the meaning of 〈Girl and Dog〉 series would be related to her husband’s death. The 17 pieces of 〈Girl and Dog〉 series are categorized into two parts; 8 pieces of 〈Untitled〉 and 9 pieces with titles. In the 〈Untitled〉 works, a woman is taking care of a dog, and in the pieces with titles, the relationship between the woman and the dog can be inferred through the titles. In conclusion, the 〈Girl and Dog〉 series were created motivated by her husband’s fight against his sickness, and metaphorically express death surrounding him and her own sexual desire which wasn’t satisfied through him. The 〈Girl and Dog〉 series can be interpreted as the transformed portrait of Paula Rego and her husband, Victor. However, according to Jung’s theory, through the 〈Girl and Dog〉 series, Rego is depicted as an obedient wife in the patriarchal system, whose life is turned out to be a kind of persona and who finds consolation in religion, so the 〈Girl and Dog〉 series can be recognized to show the process of mental self-healing. 〈Girl and Dog〉 series were produced for her sick husband, but after all, were for Paula Rego herself.
