This painting is an interesting index of changing social attitudes. When it was purchased there was no hint that the two young Africans might have identities - it was considered simply a portrait of the missionary, Robert Moffat, who spent over fifty years in southern Africa. Research subsequently identified John Mokoteri and Sarah Roby, two children adopted by Moffat and his wife. Although portrayed with sensitivity, the impression is still suggestive of the dominance of white culture. Moffat was the father-in-law of that most famous Scottish missionary, David Livingstone.
