Lady Brisco (d.1822)

Lady Brisco's portrait of around 1776 belongs to the peak of Gainsborough's London establishment, the period after his 1774 move from Bath when he was competing at the highest level of British portraiture alongside Reynolds. The large format — 235.2 by 148.5 centimeters — places the work firmly in the grand-manner tradition, and Kenwood House on Hampstead Heath, where it now hangs, was itself one of the architectural masterpieces of Gainsborough's era, remodeled by Robert Adam for Lord Mansfield in the late 1760s. The portrait represents Gainsborough's mature female style at its most accomplished: the feathery brushwork that Sir Joshua Reynolds found slovenly when seen close-up resolved at the proper viewing distance into a shimmering image of feminine elegance. Reynolds favored historical and mythological allusion for his female portraits — casting his sitters as Juno, Circe, or St Cecilia — while Gainsborough trusted the natural qualities of specific individuals to sustain pictorial interest. Lady Brisco needed no allegorical apparatus: the luminous skin, the graceful landscape setting, and the free handling of her dress created an image of English femininity that contemporaries found irresistibly persuasive.

Gainsborough's London-period handling is fully mature here, with the fluid, transparent brushwork that distinguished his portraits from Reynolds's more labored technique. The dress fabric is painted with characteristic sweeping strokes that suggest silk without describing every fold, creating an effect of effortless elegance.
