In 1819 Constable bought a house in north London’s Hampstead area, and spent part of the year there with his wife and family. It was close to Hampstead Heath, which became one of Constable's favourite sketching grounds for observing changing weather conditions. He often recorded the date and conditions of his studies on the reverse, noting in this case that he made the study at 4pm on 27 September 1821 when the atmosphere was “very warm and bright after rain”. This was the third sky and landscape study of Hampstead Heath that Constable made on this day.
The animated brushwork of this sketch conveys a feeling of movement inherent in landscape. The trees are only roughly sketched in, and there is a clear delineation between foreground, middle ground and background with the sky nonetheless given much importance. Constable states that he wanted to paint nature with its “light – dews – breezes – bloom – and freshness” rather than artificial conventions.
