St. James’s Park was near Gainsborough’s London residence, Schomberg House, in Pall Mall. The long tree-lined avenue called the Mall, which runs south of St. James’s Palace, was a fashionable place for strolling in the eighteenth century. This composition is unusual among the artist’s later works and recalls, as several contemporary critics remarked, the fêtes galantes of Watteau. The feathery foliage and rhythmic design led one observer to describe the painting as “all aflutter, like a lady's fan.” Another reported that the artist composed the painting partly from dolls and a model of the park.
The large proportion of the canvas devoted to the setting testifies to Gainsborough’s abilities as a landscape painter and to his pioneering interest in the picturesque. Attempts to identify the ladies in the central group as the daughters of George III and the background figure under the tree at right as the artist himself are attractive but unsubstantiated.
