Pets tell something about their owners, whether they are bought to make a fashion statement, as child substitutes or as an expression of unconditional love between two sentient beings. So remarked Robin Gibson, the author of this book, on its first publication in 1998. It is about the various animals that appear in portraits in the National Portrait Gallery, but it is also about the owners of the animals w ho commissioned the portraits. The association of the subject or indeed the artist of a portrait with an identifiable pet immediately adds a further dimension to our understanding of the characterisation. For example, in a self-portrait by Hogarth there is a pug probably painted over by the artist and visible only under X-ray relieving itself on a pile of old master paintings. A succinct comment, Gibson writes, on those collectors who preferred second-rate foreign imports to contemporary works by British artists. From the Elizabethan soldier and diplomat Sir Henry Unton to the children of King Charles I; from the little terrier that records Lady Caroline Lambs first extra-marital affair to Queen Victoria's dogs, photographed with her Ghillie John Brown; from the extraordinary images of ballet dancer Anna Pavlova and her pet swan to the poet and critic Edith Sitwell and her favourite cat, this book charts the British love-affair with the domestic pet.
