In the late 1920s (probably 1928) Wyllie visited the Mediterranean. The resulting works included two paintings exhibited at the Royal Academy: 'The temple of Pallas Athene from the sea' (1929), and 'Athens from the Gulf of Aegina', exhibited posthumously in 1931. He also produced a set of six drypoints of the Mediterranean, among them views of Gibraltar, Naples and Malta. This watercolour demonstrates a loosening of his handling of the medium in his later years.
