[1] The "Trippenhuis" was used as a picture gallery before the Ryksmuseum was built. It was an old patrician family mansion belonging to the Trip family. Several members of this family filled important posts in the government of the old Republic of the United Provinces, and some were burgomasters of Amsterdam.

[2] "Arti et Amicitiæ" is a society of modern Dutch painters. Occasionally the members organise exhibitions of the work of contemporary countrymen or of foreign artists, and every year there is an exhibition of their own works. These shows are held in the society's own building in Amsterdam at the corner of the "Rokin" and "Spui."
