Rare iconography.
Unidentified character. Perhaps Jean-Joseph Sue, the father (known as Sue le Jeune, or Sue de la Charité, 1710-1792: grandfather of Eugène Sue). This surgeon and professor of anatomy and dissection had one of the most important anatomy offices of his time* and he provided descriptions of fetuses preserved in fluid.
Delicate work on the complexion, in the drawing of the hands and in the meticulous rendering of details – especially in the curls of the wig and the lace of the garment.
Relining. Trace of restoration.
