At the smaller German courts we encounter mostly the same artists that also worked in Prussia. They were particularly active as portrait painters. Paintings from Johannes Mijtens1 and Daniël Mijtens II (1644-1688) are even today still numerous in the Dessau collections . Henriette Catharina, third daughter of Frederik Hendrik van Oranje, married the Anhalt Prince Johann Georg II in 1653. Just like her sister who married in Berlin, she had a predilection for the art of portraiture of the two Mijtens, by whom she and her relatives were painted repeatedly. In the Dessau Castle there are still many portraits (also studio works) of Frederik Hendrik’s four daughters, their husbands and children .2

To the most popular portrait painters of the Oranges and Palatines also belonged Adriaen Hanneman (c. 1604- 1671), who immortalized both Henriette Catharina and her husband Johann Georg II , as well as the Great Elector 3 and various children of the Winter Queen who were married to German princes.
Thanks to favourable conditions a large number of these family heirlooms have been preserved in the Dessau palaces, but we also encounter them at other German courts, whose families were related to the Oranges.4 When Maria van Oranje-Nassau (married to Ludwig Heinrich Moritz von Pfalz-Simmern in 1666)  died childless in 1688, her possessions were divided between her still living sisters, Henriette Catharina and Albertina Agnes. This growth of the Dessau collection is revoked by a loss. When Henriette Amalia, daughter of Henriette Catharina, married her cousin Hendrik Casimir II van Nassau-Dietz in 1684, she obviously took some of the family heirlooms to Friesland.5 But most of it stayed in the possession of her brother Leopold I von Anhalt-Dessau, whose daughter Henriette Amalie (1720-1793) founded the well-known Amalienstiftung in Dessau, which kept a large part of the inheritance together. In addition to Berlin, other parts of the former Orange estate are in Eisenach (since a daughter of Albertina Agnes married into a family there) and in castles in Hannover.
One used to send one another one’s portrait as a present. In particular, the Great Elector abundantly made use of this convention, which indirectly benefited the dispersal of Dutch art. In the same way Louise Henriette established a portrait gallery in her small castle Oranienburg, her sisters did so as well. Oranienbaum Castle near Dessau housed the collection of Henriette Catharine. The best impression of a traditional painting gallery is still granted today at Mosigkau Castle, although it was not built until the 18th century. 6

The younger generation of the Dessau princes was mainly painted by Jacques Vaillant, Daniel Mijtens II and Maria van der Laeck (c. 1637/8-1664). Van der Laeck must have lingered at the Dessau court in the 1670s.7 There is a pretty family portrait by her hand of Henriette Catharina surrounded by her children  and a not less fine portrait of her son Leopold (the later ‘old Dessauer’) , which stylistically stands between Nicolaes Maes and Johannes Mijtens.8

The Leiden painter Abraham Snaphaen (1651-1691)9 was also appointed as an Anhalt-Dessau court painter, probably in the 1680s, after the death of Maria van der Laeck. In any case it is striking that his genre paintings in the taste of Gerard Dou that originated in his home town cannot be distinguished from the usual Leiden production of the time , while his Dessau portraits [9-12] are rather clumsy and incongruous. Only superficially they still remind us of works by Frans van Mieris and Godefridus Schalcken. 10 Snaphaen ends up the same as so many other minor talents, who, when abroad, lack the support of the broad-flowing painting culture of the Netherlands and slip down to becoming a negligible figure.

3 [Gerson 1942/1983] All three in Dessau Castle. The portrait of the Great Elector (formely in Wörlitz) of 1659 is probably also a gift of the vain man, this time possibly on the occasion of the wedding of his sister-in-law which took place the same year.

6 [Van Leeuwen 2017] Gerson states ‘das adlige Fräuleinstift Mosigkau’ (the foundation for unmarried noble women); until 1945 the castle was indeed inhabited by unmarried noble women, according to the wish of (unmarried) Princess Anna Wilhelmine, who died in 1780. The castle is a museum since 1951.
7 [Van Leeuwen 2017] No one of the name Van der Laeck was at the court in Dessau. Before 1928 the two paintings mentioned here by Gerson were attributed to Reynier van der Laeck (c.1615/20-1647/48), based on the fact that a signature on the family portrait was read as ‘van der Laeck’. Because Reynier appeared to have died before the 1650s, a new attribution to his daughter Maria van der Laeck was proposed (Thieme/Becker 1907-1950, vol. 22 , p. 192-193). However, Maria also died too young to have been able to paint the portraits dating from c. 1670 (Buijsen/Dumas et al. 1998, p. 322). In 1999 the signature on the family portrait was read not as ‘van der Laeck’ and ‘16.8.[1678?]’ but as ‘FBleck [?] Fe. 1668 [9?]’ (Schacht/Bartoschek et al. 1999, p. 326, no. 9/9, ill.; Bauer 2005, p. 86-89, no. 131, ill.).
