Manda Lamétrie, farmer's wife (French: Lamétrie, Manda fermière) is the title of a painting by Alfred Roll. This imposing portrait from 1887 was a great success at thesalon a year later. A critic of the Gazette des Beaux-Arts called it even the painting of the year.  since 1980, it is part of the collection of the Musée d'Orsay in Paris.
Alfred Roll had a summer house in the neighborhood of Sainte-Marguerite-sur-Mer on the Normandy coast not far from Dieppe. In the same village possessed Amanda (Manda) Lamétrie a small farm. On the portrait she has just one of her three cows milked in the Orchard. With purposeful look she walks off with a bucket full of milk on the spectator. The success that the painting to the life of the farmer's wife, changed little. Until her death she remained single and took care of her farm, which she supplemented her income with guarding summer houses and catching shrimp. 
In the eighties of the nineteenth century painted Roll several women portraits in naturalistic style. He used the bright palette of the Impressionism, however without the loose technique of which flow to take over. The portrait of the then 20-year-old Amanda Lamétrie is one of the highlights of this series. The artists of naturalism had a preference for portraying scenes from everyday life. With Zola they were of the opinion that the pursuits and the surroundings of the main characters, in General, determined their fate. The monumental, frontal view that Roll in this portrait uses, transforms Amanda Lamétrie to an icon of the French rural population.
