Derick Berck of Cologne

According to the inscription on the cloth-covered table, this portrait of a bearded man was painted in 1536, when the sitter was thirty years old. He holds a letter in his left hand, while a scrap of paper inscribed with a line from Virgil’s Aeneid lies nearby. The address on the letter identifies the sitter as Derick Berck, a German merchant who lived and worked at the Steelyard (Stahlhof), the London headquarters of the Hanseatic League. What has been identified as his personal merchant’s mark is next to his thumb on the paper he holds.

Heinrich Averdunk and Walter Ring, historians of the city of Duisburg, first identified the sitter in 1927 as a member of the Berck family of Duisburg. Günther von Roden (1963) subsequently concurred, citing a document of 1558 that mentions the family’s address there, and noting that the Bercks were respected merchants with ties to London. Later scholarship uncovered other documentary evidence placing Derick Berck in Cologne, some fifty miles south of Duisburg. He may have become a citizen of that city, for a 1543 document in the Cologne Archives refers to him as "Dirk Bergh aus Köln" in connection with a dispute involving him and Derich and Johannes Born, two brothers who were also members of the Steelyard. In 1545 Berck is mentioned in another document as renting a room in London.

The attribution of this portrait to Holbein has never been challenged: the work is consistent stylistically and technically with the artist’s other Steelyard portraits of the 1530s. No preparatory drawing on paper survives for it or for the other portraits in the group. Indeed, the underdrawing does not show the characteristics of a transfer from a cartoon, as do the portraits that Holbein made of individuals associated with the court of Henry VIII. The Met's portrait may therefore have been worked up directly by Holbein at one or more sittings with Berck. Notwithstanding its damaged condition, which Ralph Nicholson Wornum noted as early as 1867, this forthright representation is among the most appealing of the Steelyard portraits.

Various meanings have been proposed for the quotation on the cartellino, an excerpt from a passage that reads in full, "Perchance even this distress will someday be a joy to recall." Alfred Woltmann (1868) thought that the words were simply intended as a memento of a friend who had died. Deborah Markow (1978) interpreted them as a "sentimental reassurance to those left behind of Berck’s eventual safe return [to Germany]." Thomas Holman (1979), however, stressed that the passage came from a speech by Aeneas that was in effect a "statement of encouragement" to his comrades, who were headed for considerable challenges before arriving at their new home. Holman thus interpreted it as meaning that Berck would fondly recall his days at the Steelyard only after having returned safely to German soil. Similarly, if the portrait were to be sent home, such a sentiment might be of some solace, as Markow suggested, to family members anxiously awaiting his return.

Katrin Petter-Wahnschaffe (2002) has recently challenged Markow’s and Holman’s interpretations, noting that the reference to future happy memories of London would apply to the sitter and not to his family and that it was thus unlikely that the portrait would have been sent home to loved ones. She argued further that, as part of a speech by Aeneas, the passage implied an address to more than one person, an idea also supported by the orientation of the script toward the viewer. Following Craig Kallendorf ’s observation that Renaissance commentators regarded the Aeneid as a source of moral and ethical precepts, Petter-Wahnschaffe interpreted the passage as an "appeal to the forbearance, constancy, and steadfastness of the addressees." This, of course, fits well with the routinely precarious situation of the Hanseatic merchants, who frequently encountered dangers at sea as part of their occupation. Petter-Wahnschaffe thus concluded that the portrait was intended for the Steelyard members themselves, who would have found significance in the inscription. Far more speculatively, she theorized that the quotation may have been chosen to further Berck’s aspirations for leadership within the group.

Still others have seen references to human mortality in the inscriptions. Susan Foister (2004) was the most recent to link the Virgil quotation with the phrase "befelt de[m] bode[n] (deliver to the carrier)" on the letter, mistranscribed by Paul Ganz as "besad dz end (consider the end)" and misunderstood in almost all the subsequent literature. Foister interpreted this as expressing the sitter’s wish to be remembered fondly after his death. Kurt Löcher (1995) interpreted the same words as advice to Berck to recall his Christian duty and bear in mind the salvation of his soul. Wornum alone was on the correct path when in 1867 he transcribed the words as "befall ds briff (deliver this letter)". Taken together, the recent findings and new interpretations concerning these texts reinforce the notion that the Steelyard portraits were intended to hang together and to be appreciated by the members of this group rather than sent home to family in Germany.

The portrait was painted on a panel composed of three boards, the central piece of which was approximately six inches wide, and the two flanking pieces approximately five inches wide. Before entering the collection, the painting was transferred from the wood support to canvas, imposing an uneven, textured surface in the process.


The painting is not well preserved. The surface is severely abraded throughout along the wood grain and panel joins. There is a large loss in the arm at the right (associated with a vertical split in the panel), and a series of losses are found in the mouth and right eye; a half-inch-wide area of restoration is present around the perimeter. Holbein’s characteristic deft brushwork, used to enrich the individual hairs and eyelashes of the sitter and the fur trim of his clothing, is badly damaged. The flesh tones, with their higher concentrations of lead white, the green cloth in the background at the left, and the opaque red cloth draped over the table are better preserved. The meticulous embellishments in black, such as the trim and tassel on the shirt and the flowing script on the paper fragments, are also fairly well preserved, as is the inscription at the lower right.


Infrared reflectography revealed a small amount of underdrawing in the face and hands (see figs. 1–2 above) as well as an area of reserve for the hands. It also confirmed that both pieces of paper were added on top of the fully painted ledge and hands.
