5.1 Painters from the Netherlands in Frankfurt
Frankfurt am Main became the sanctuary of many Flemings, who had to leave their homeland because of their faith.1 They also settled in the neighbouring Hanau and in the Palatine, Frankenthal. In Hanau, production of ceramics developed and in Frankenthal a Dutch school of landscape painting. Gradually also Northern Netherlandish artists came there, many of them only temporarily on their way to the south. Others went to the coronation of the emperor in Frankfurt in 1658, hoping to receive commissions for portraits (Wallerant Vaillant, Pieter Donker).2 One of these volatile visitors was David Bailly, who came from Hamburg in 1608 and then travelled through Nuremberg, Augsburg and Tirol to Venice and Rome.3 Jean Vaillant II (1627-1675), whose family came from Lille, possibly travelled to Frankfurt in 1658 with his brothers Wallerant and Bernard.4 However, he quit painting and became a merchant. Willem Schellinks (1627-1678) met him in nearby Frankenthal in 1665.5
Although these few examples only concern passing travelers, those wandering journeymen still contributed somewhat to the dispersal of Dutch art. Several Frankfurtian artists went to the Netherlands to have a look around. Let’s stick to the portrait painters first. Jeremias van Winghe (1578-1645), who was born in Brussels but migrated with his father to Frankfurt, finished his training in Antwerp and Italy before he finally settled in Frankfurt in 1608. 6 The portraits he painted in Frankfurt [1-3] are however executed in a good Dutch manner; they can best be compared to works by Dirck Dircksz. Santvoort (1609-1680).

Joachim von Sandrart I (1606-1688), who owed his training to Gerard van Honthorst, repeatedly stayed in Frankfurt.7 When he went for the second time to the Netherlands in 1637, he took the young Matthäus Merian II (1621-1687) along to Amsterdam. But, after receiving a recommendation to Anthony van Dyck from Michel le Blon, Merian travelled on to England. Then he wandered around in France and Italy for a long time, before he finally settled down in Frankfurt in 1650 [4].8 After all this, one cannot expect him to have developed a pure Dutch portrait style; on the contrary, many of his portraits passed on under the name of Van Dyck.9 Nevertheless the portraits of Swedish generals [5], which were probably commissioned by field marshal Wrangel [6], are clearly related to the Dutch type of Gerard van Honthorst and Wybrand de Geest.10 The portrait of Joachim Merian, that probably originated later, is done in the style of Caspar Netscher (Senckenbergische Stiftung) [7].11

As is known, Merian was born in Switzerland, and even before he returned to Frankfurt from his journey in France, his compatriot Samuel Hofmann (c. 1595-1649), who also visited Holland [8], settled here in 1638 [9].12 We have to keep in mind these mutual relationships between France and Switzerland, because they still play an important role in the 18th century. Samuel Hofmann’s daughter Magdelena (1633-1688)13 went with her mother to Amsterdam after her father’s death, where she painted portraits and flowers.
The German Jakob Christof Le Blon (1667-1741) took the reverse route from Frankfurt to Zürich, where he learned from Conrad Meyer (1618-1689). In 170514 we find him in Amsterdam [10-11] and later he was in England and France. His Dutch training will have had little impact on his homeland.
Hüsgen and Gwinner deal with a portrait painter Daniel Thielen (1623-1711) in some detail. His portraits are supposed to be in the style of Rembrandt and appear under his name in the art trade. No such works have occurred thus far [12], and also none of his still-lifes and bird pictures are known today [13-15].15

4 [Van Leeuwen 2017] Jean Vaillant was thought to have died c. 1672 in Hanau, but 16 April 1675 he was buried from a house at the Fluwelen Burgwal in Amsterdam (the house of his brother Wallerant?) at the French or Wallonian Reformed Church, leaving behind under-aged children (Waalsch Gereformeerde Kerk on Vaillant, Jean - 16-04-1675 - Fransch of Waalsch Gereformeerde Kerk - DTB 1130, p.317 -318).

6 [Gerson 1942/1983] Zülch 1935, p. 481. [Van Leeuwen 2017] According to Thieme/Becker he was not trained in Antwerp but in Amsterdam, where he was a pupil of Frans Badens (Thieme/Becker 1907-1950, vol. 36 [1947], p. 55), a source that obviously was not available to Gerson at the time. Furthermore, he probably was already in Frankfurt in 1605, since there is a 1605 dated portrait of Sebastian de Neufville (1545-1609) from Antwerp who had settled in Frankfurt (RDKimages 127262).

8 [Van Leeuwen 2017] Many details about his life and whereabouts (included in RKDartists&) are documented: Wackernagel 1895, Nieden 2002 and L.H. Wüthrich in Saur 1992-, vol. 89 (2016), p. 148. Merian stayed about two years in Amsterdam and two years in London as well, until the death of Anthony van Dyck. Already in the 1640s he was on and off in Frankfurt.

10 [Gerson 1942/1983] Paintings in Gripsholm; images in Granberg 1911-1913, vol. 3 (1913), p. 78. [Van Leeuwen 2017] Several portraits of generals seem of less quality, as if they are copies after originals that might have been painted for the generals themselves. The Portrait of Field Marshal Count Hans Christoffer von Königsmarck in Skokloster (RKDimages 265925) seems closer to Van Dyck’s style.

13 [Van Leeuwen 2017] Gerson erroneously calls her Susanna. The date of her burial, 24 November 1688, comes from the Ecartico database. No artworks by her hand are known to us.
14 [Van Leeuwen 2017] On 13 February 1705 he married Gerrarda Vloet (1679 – 1716) in Amsterdam (Ecartico). On Jakob Christof Le Blon: Lilien 1985.
15 [Gerson 1942/1983] Hüsgen 1780, p. 90-91, 234, 282; Gwinner, p. 228-229. [Van Leeuwen 2017] There is a portrait by Thielen (which has little to do with Rembrandt) of the Frankfurter theologian Philipp Jacob Spener (1635-1705) in the Historisches Museum in Frankfurt (Grosskinsky/Michels et al. 2003, p. 178-180, nos. 28-29, ill.). Two still-lifes in the Anhaltische Gemäldegalerie Dessau probably derive from the collection of Henriette Amalie von Anhalt-Dessau. Apparently Gerson assumed that Thielen was trained in the Netherlands.
