"Portrait of a Little Girl, Elise Købke, with a Cup," Carl Christian Constantin Hansen, 1850.
Hansen (1804-1880) was one of the big names in the Danish Golden Age of painting (mostly the first half of the 19th century), which itself borrowed heavily from German Romanticism, the influence of which can be seen here.
His father was a portrait painter, and his godmother was Constanze Mozart (!), and his family traveled from Rome to Vienna to Copenhagen while he was still an infant. After his training as an artist, he traveled all over Europe, painting landscapes, mythological scenes, altarpieces, and portraits like this one. He did a series of paintings based on Norse mythology, intending to create a sort of national art of Denmark.
The poor thing here looks profoundly bored and uninterested. I know nothing of her, but I'm guessing from her name that she was a relative of Hansen's wife.
I still prefer the Skagen school, myself!
