Arthur Streeton’s images celebrating the blue and gold palette of Australia’s sun-drenched landscape struck a nationalistic chord during the lead-up to Federation. In early 1896 Streeton travelled to the upper reaches of the Hawkesbury River, between Richmond Bridge and Windsor, where he was inspired by the expansive view looking towards the Blue Mountains. ‘The purple noon’s transparent might’ takes its title from a poem by Percy Bysshe Shelley that embraces the natural world – sun, sky, water and mountains – and was painted in two days ‘during a shade temperature of 108 degrees’, in a state of ‘artistic intoxication with thoughts of Shelley in my mind’.
