A portrait sketch of the great tragic actress from 1784; I find this as expressive in its way than the much more famous painting of her by Sir Joshua Reynolds.
Here is how Reynolds portrayed her in the same year, as the Muse of tragedy.
Mrs Siddons in action! Plainly not a woman to be trifled with.
Romney is of course a most unheroic painter most of the time. His portrayals of mothers and children I find most touching, there seems to be a genuine relationship between them, the infants are not just parked on their laps.
