Gainsborough was noted for the speed with which he applied paint, and he worked more from observations of nature (and of human nature) than from application of formal academic rules. The poetic sensibility of his paintings caused Constable to say, "On looking at them, we find tears in our eyes and know not what brings them." Gainsbrough said, "I'm sick of portraits, and wish very much to take my viol-da-gam and walk off to some sweet village, where I can paint landskips (sic) and enjoy the fag end of life in quietness and ease." His liking for landscapes is shown in the way he merged figures of the portraits with the scenes behind them. His later work was characterised by a light palette and easy, economical strokes.
