In his article Professor Larsen points out the close relationship between Frans Hals and the Post family in Haarlem. Adopting the role of what today would be a press photographer, the painter Frans Post accompanied Prince Maurits of Nassau, who between 1637 and 1844 was the governor of the Dutch West India Company, to Brazil. It was his task to travel through Brazilian territories and capture the landscape and the people with topographic faithfulness. His pictures were meant to convey to the people in his native country the exoticness of Brazil, in order to persuade them to emigrate to and settle in the country of parrots. Comp. Erik Larsen, Frans Post, Interprète du Brasil, Amsterdam/Rio de Janeiro 1962, pp. 60-62). Because the facial features of the present sitter resemble those of Pieter Post, an architect and the brother of Frans (both brothers were friends of Frans Hals), Prof. Larsen concludes that she must be the artists' mother, Francijtje Post. Frans Hals also portrayed the two brothers.
