How does Pieter Tjarck elucidate its Painting?
The painting shows a fashionably dressed gentleman leaning over the back of a chair holding a rose. This painting was documented by Ernst Wilhelm Moes in 1909 and Hofstede de Groot in 1910, who wrote:PIETER TJARCK. M. 77. Half-length; in an oval of painted stone. A man seated, facing three-quarters right, looks at the 
spectator. His right arm rests on the arm of the chair; in the hand is a rose. He has a big moustache' and pointed beard. He is in black with a big broad hat and a soft close-fitting ruff.
