Description:
In accordance with traditional marriage diptych portraits the boy is shown in the position usually occupied by the woman. Consequently the allied coats of arms of the dukedoms of Saxony and Mecklenburg on the reverse of the panel do not correspond with that of the boy but that of the mother. The diptych can be closed and is decorated along the top edge above the coats of arms and as such is in keeping with the tradition of marriage portraits. Assuming a strict frontal pose the fair curly headed boy is so close to the viewer that his outline is cropped on all four sides at the edge of the image. He faces the viewer directly with slightly raised eyebrows. The boy's hat is decorated with fantastic ostrich feathers and golden brooches. Decorative slits in his green overcoat reveal a red lining. In his hands he holds a small dagger. [1] The two sitters are identified by the coats of arms on the back of the right-hand portrait. They confirm the resemblance of the sitter in the left-hand panel to portraits of Johann the Steadfast (1468-1532) Elector of Saxony, who ruled jointly with his brother Frederick the Wise (1463-1525). The right-hand panel must therefore depict his son, Johann Friedrich the Magnanimous (1503¿1554), whose mother Sophie von Mecklenburg died at his birth in 1503.

Provenance:
- the portraits are first recorded as 'Zwey Churfürsten aus Sachßen Conterfät an Einem Stückh' ('Two portraits of the prince electors from Saxony in one piece') in an inventory listing items in the collection of the Margrave of Baden-Durlach, Karlsburg, Baden-Durlach, which had been transferred in 1688 under Margrave Friedrich VII (ruled 1677 - 1709) to the Markgräfler Hof, Basel, in order to avoid destruction by French troops in the Nine Years War or War of the Palatine Succession.[1]
- Although in 1715 Margrave Karl III Wilhelm (ruled 1709-38) founded a new capital for his court at Karlsruhe and in 1775 his successor Karl Friedrich (ruled 1738-71) completed a new palace there, many of the paintings, including NG 6538 and 6539, remained stored at Basel. In 1733 and 1776 new inventories were drawn up: the two pictures are recorded in the inventory of 1733 as 'Zwey Churfürsten in Sachsen in Schwartz und vergoldeter Rahm so sich zusamen legen laßen' ('Two prince electors in Saxony in a black and gilded frame which can be folded together').[2]
- sold at Basel in 1808. They were purchased, along with nearly a hundred others, by Peter Vischer (1751-1823), later called Vischer-Sarasin, of Schloss Wildenstein in Switzerland, a merchant and municipal councillor of Basel. They remained at Schloss Wildenstein in the possession of the Vischer family (the last of whom, Peter Leonhard, died in 1990)
- auctioned at Christie's, London, on 6 July 1990, no. 42. [3]
- they were purchased through Christie's in 1991. [4]

Interpretation / History / Discussion:
The related colouring suggests that the panel paintings were not created independently of one another. It would appear that the father, Johann the Steadfast, attached importance to the fact that this diptych should manifest his affection and his hopes for his son and his future destiny as elector of Saxony.
[see Brinkmann, 150]

[Laura Thiepold, cda 2012]
Despite differences in the depiction of father and son there are obvious similarities: the green in the background of the father is repeated in the son’s robe and the black in the background of the son is repeated in the robe of Johann the Steadfast. The dark clothing and the relatively smaller depiction of the figure of the father make him appear as it were to withdraw into the background, whereas the green robe and the close-up representation of the son make him stand out against the dark background.
[see Baker, Henry 2001, 156], [see Langmuir 2006, 115], [see Brinkmann 2007, 150]
[Laura Thiepold, cda 2012]
The child’s head is positioned higher than that of his father, which might indicate that he is smaller and is therefore seated on a stool. [see Langmuir 2006, 114]
[Laura Thiepold, cda 2012]
The portrait appears spontaneous, suggesting that Cranach’s portrayal of the boy was specifically for this painting. [see Langmuir 2006, 114]
[Laura Thiepold, cda 2012]
Brinkmann interprets the optical discrepancy between the two sitters as a reference to the composition of diptychs in which the Virgin or the Man of Sorrows is venerated by a half-length donor. [see Brinkmann 2007, 150]
[Laura Thiepold, cda 2012]
The dagger in his small hands alludes to his transition into adulthood. [see Rebel 1994, 135]
[Laura Thiepold, cda 2012]
It is striking that father and son do not look at each other and are at the same time shown from different perspectives. The double portrait of Martin Luther and Katharina von Bora, created in the Cranach workshop in 1526 (Private Collection, Hamburg, FR Nos. 189, 190) is similar in this respect. Luther like Johann the Steadfast is shown as a bust portrait in three-quarter profile on the left. His gaze is fixed on a point beyond the picture plane to the right. The depiction of Katharina von Bora exhibits similarities with Johann Friedrich. One theory which would explain this discrepancy within the diptych is that the woman who is by nature smaller and daintier would manifest greater presence if shown as a half-length figure. As the six year old Johann Friedrich is represented in place of a wife and is in reality considerably smaller than his father he is shown frontally as a half-length figure. In contrast Luther’s wife is shown in three-quarter profile, but it is apparent that both face the viewer. Bünsche and Grimm presume that in the case of the double portrait of Luther and his wife the differences are due to the fact that a portrait of the Reformer already existed. According to Dunkerton et al. a frequently used preparatory sketch served as a template for the painting of Johann the Steadfast, whereas Johann Friedrich was portrayed specifically for this painting. Bünsche and Grimm’s theory that the asymmetrical depiction relies solely on the existence of an archetype of Luther seems absurdin the light of the serial production of paintings of both Luther and his wife. Koepplin proposes the theory for the London diptych that the discrepancy may result from different authorship. However after comparison with other diptychs the aforementioned theory that the weaker one of the pair on the right was depicted as a half-length figure also seems plausible. [Friedländer/Rosenberg 1979, Nos. 189, 190 150], [see Exhib. Cat. Kronach 1994, 352-353], [see Rebel 1994, 134-135], [see Dunkerton et al. 1999, 16]
[Laura Thiepold, cda 2012]
Gunnar Heydenreich assumes that both panels were probably constructed within a narrow time frame by the same carpenter as they each consist of three butt-joined planks, varying in width and these widths correspond on both panels. [Gunnar Heydenreich, Examination Report, 1994 (unpublished)]
[Laura Thiepold, cda 2012]
This depiction of Johann Friedrich is unique in Cranach’s oeuvre. According to Dunkerton et al. it is not based on a preparatory sketch as it was painted from life. [see Dunkerton et al. 1999, 16]

[Laura Thiepold, cda 2012]
Claus Grimm assumes that only the preparatory design for the composition of the portrait of Johann Friedrich is by Cranach. According to Grimm the underdrawing and the painting was executed by an assistant. However this has cannot yet been proved as neither an infrared reflectogram nor examination under the stereomicroscope has revealed an underdrawing. This does not mean that there isn’t one. [see Exhib. Cat. Kronach 1994, 371], [see Heydenreich 2007, 106-107, 339], [see Sandner 1998, 56-59]
[Laura Thiepold, cda 2012]
The diptych closes from right to left, which is why the verso of Johann Friedrich shows both coats-of-arms pointing up. When closed together both panels in their respective frames form a small box. [see Koepplin, Exhib. Cat. Basel 1974, Fig. 2], [Dülberg 1990, 188, Fig. 452]
[Laura Thiepold, cda 2012]
Fasert presumes, that the diptych may have been a diplomatic gift, because it shows the future ruler Johann Friedrich and his father. [see Fastert 2007, 143]

Material / Technique:
  • Date: 2016
  • Technical examination / Scientific analysis
  • Paint Layers and Gilding
  • The medium of the paint of the green background and black robe in NG6538, and of the green sleeve in NG6539, was identified by GC–MS analysis as linseed oil.[1] A sample of red paint from the pattern on the sleeves in NG6539 was found to contain linseed oil together with with a little pine resin.
    Pigments
    Verdigris forms the basis for the green background of Johann the Steadfast (NG6538). In the opaque underpaint it is mixed with lead white and lead-tin yellow, while in the final translucent layers it is used alone. Very similar green paint mixtures were used for the main colour of the costume of Johann Friedrich (NG6539). The intense red strips on the boy’s costume consist of vermilion of exceptional quality and the same pigment combined with red earth and black makes up the more brownish-red stripes. There are pale yellow highlights of lead-tin yellow on the gold chain. The basic pale pink tone of the flesh paint is a mixture of white and a little vermilion, with some black pigment in addition in the shadows.
    Painting technique
    In common with many pictures by Cranach the flesh is thinly painted. Details such as the twisted braids decorating Johann the Steadfast’s hat have been skilfully painted, with rapidly applied touches for the pearls and impasto yellow highlights for the gold, for example for the threads at the end, where the lighter green underpaint has been deliberately left exposed around them to indicate the overall shape of the tuft at the top right of the hat. Similarly, the feather is formed of wet-in-wet strokes of grey and black and has circular markings with the impasto typical of a bodied lead-tin yellow paint.
    [1] There was no indication of heat-prepolymerisation of of the addition of resin.
  • Support
  • The panels are each formed from three thin boards of wood with grain running horizontally.
    The backs of both panels are painted black. On NG6538 there is a later inscription in red which reads N27 28. Two shields are painted on the back of NG6539
  • Ground and Imprimatura
  • The grounds of the obverses are of chalk. The reverses are painted directly on to the wood with no ground. There does not appear to be any priming.
  • Underdrawing
  • - nothing that could be definitely identified as underdrawing was found with infrared reflectography.
  • Framing
  • The frames are original. The profiles, with their simple deep scotia moulding and raised outer edge enriched with a narrow half round, are similar to those found on other frames of works by Cranach of this period.[1] They are joined with a double mortise and tenon joint.[2] It can be seen in X-ray images that neither frame fits the panel exactly: there are gaps top and bottom, although the frames fit tightly on the left and right; however, this can be explained by the natural contraction across the grain of the panels, and is not any indication that the portraits were not originally in these frames.
    The outer edges and the backs of the frames are painted black. The inner mouldings were originally gilded although what is now visible is mainly the golden-yellow oil mordant (adhesive) [3], and only fragments of the gold leaf remain. Traces of this mordant pass beneath the black background on NG6539 confirming that it is original and was already in place when the background was painted. On NG6538 there are traces of the original final translucent green paint of the background on the gold, indicating that it was applied when the frames were complete. However, painting of the portraits and decoration of the frames were probably carried out concurrently, since there are also traces of gold from the frame on top of the black background of NG6539 at the left edge The frames are joined with iron hinges and handmade iron nails; this was done after gilding as the tips of the nails are visible in the mouldings.[4]

    [3] FTIR analysis suggested that the binding medium of the mordant is oil.

                      • Support
                      • - the support is a softwood panel. An examination to establish the species was not possible as the painting is fixed in the original frame. The wood is of high quality. It is a fine-grained wood, which does not exhibit any knots in the x-radiograph. The panel consists of three planks joined in the shortest direction of expansion (horizontal).
                        - the widths of the planks are c. 13.8 cm, 17.5 cm and 13 cm (12.8 cm)
                        - there is no reinforcement visible along the joins. The reverse has a very smooth finish. The edges of the panel are straight. The format of the panel has not been altered.
                      • Underdrawing
                      • - an underdrawing could not be detected employing infrared reflectography
                      • Ground and Imprimatura
                      • - the ground layer on the recto is white and relatively thinly applied
                        - there are numerous tiny bubbles in the chalk ground, which were sanded down. These appear consistently white in the x-radiograph and must therefore be filled with paint containing lead
                        - the barbe is preserved on all four sides, but is pronounced to a varying degree
                        - with respect to the imprimatura examination achieved the following results: ‚The tiny, sanded down bubbles in the chalk ground are filled with a medium that absorbs x-rays, and which is irrespective of the colour of the paint. This observation suggests an isolating layer with lead-containing oil or an imprimatura containing lead. In the cross-section (of the sample taken from the edge) an imprimatura could not be verified.’
                      • Paint Layers and Gilding
                      • - the flesh paint contains primarily lead white and relatively coarse vermilion (A. Roy, verbal communication). The flesh paint was applied with an initial pale flesh coloured tone and subsequently modulated with brown glazes. The highlights employing an admixture of white, red, single blue pigments and possibly some black were applied in part over the brown glaze and were then again shaded with greyish brown glazes. (This multiple layer structure is particularly visible in the area of the eyelids.)
                        - in the black and green areas of the painting a brush of c. 5 mm in width was employed

                      • - original frame (mortise and tenon frame) with a steeply sloped rainsill. The dimensions of the frame are 49.3 x 38.6 cm. The members are 3.8 to 3.9 cm wide and 3.0 cm deep. The frame has a double mortise and tenon join.
                        - both panels are held together with the original iron hinge

                        - Coatings: the flat edge, the side edges and the reverse are black; the flute and the inner edge or the bottom champfer are gilded over a white ground and a yellowish or ocher coloured mordent. The mordent covers the background in places. According to a verbal communication by Ashok Roy the mordent on the frame is the same as that on the background and contains large quantities of Si (silicon), quantities of Fe (iron) and Ca (calcium) and some lead.’

                                      • The panels and frames have suffered worm damage, but are otherwise in good condition. The dull yellow paint on the frames is the exposed mordant or adhesive for the original gilding; only traces of gold leaf remain. The paint of NG6538 is in excellent condition, with only a few tiny flake losses. There may be some fading of a red lake pigment in the flesh paint of the sitter's hands. NG6539 has more small losses, from the green paint of the sitter's costume, along the grain of the wood, but is still in very good condition.

                                        • Support: The panel and frame are of the same construction as NG 6538 and are similar in condition. In addition, the centre of the upper moulding of the frame has been splintered and damaged by a screw or nail driven in from the back. Paint and ground: The paint and ground are also in similar condition to NG 6538 but with no sign of current blistering. However there are scattered small flake losses from the thick green paint of the costume. The discoloration of the final 'copper resinate' glazes is rather patchy and uneven and they may have been damaged slightly in a past cleaning. Surface coating: The painting has the same varnish and surface dirt layers as NG 6538. Treatment proposed: Remove surface dirt and discoloured varnish and retouchings. Consolidate and repair the frame. Revarnish and retouch where necessary. [Examination made by Jill Dunkerton, 23 Feb 1995].

                                          • Cleaned and restored by Jill Dunkerton, frame consolidated by Clare Keller Detailed report: The cleaning proceeded as in NG 6538, only here the retouching was found to be more discreet, limited mainly to the small flake losses along the grain of the panel. The same difference in paint texture and colour between the face and hands was apparent and so again a thin layer of probable surface dirt was left. The painting is equally well-preserved and painted with even greater speed and vigour: the corners are almost missed by the green glaze, in a gap between the twisted links of the chain no glaze was ever applied, leaving a triangle of pale green, and some of the black paint of the pentimento filling in the area between the sleeve and body barely covers the underlying green. For the treatment of the frame see NG 6538. The disruption in the centre of the upper edge was found to be caused by an old and possibly original nail and so it was decided not to attempt its removal. The restoration was carried out in the same way and using the same materials as NG 6538. Again care was taken not to reduce by retouching any of the vitality of the brushwork.
