Resúmenes

En los años 1960 dos mazorcas de maíz similares, hechas en plata, atribuidas al período chimú-inca han sido vendidas por dos comerciantes de arte de Nueva York al Museum für Völkerkunde, hoy Ethnologisches Museum, de Berlín, y al Denver Art Museum. La composición de las dos piezas muestra el uso de diferentes aleaciones, lo que sugiere la reutilización de diferentes objetos precolombinos. Solo las soldaduras utilizadas para unir las diferentes partes de las mazorcas contienen una cantidad de zinc que podría indicar una intervención moderna. La hipótesis de este artículo es que la estabilidad económica en la década de 1960 combinada con el deseo de restablecer las pérdidas de la Segunda Guerra Mundial en colecciones de museos, especialmente en Alemania, facilitó el camino para compras dudosas incluyendo falsificaciones.

This study was initiated by the interest and persistence of Andrew Hamilton, who brought in contact the museums staffs of the Ethnologisches Museum in Berlin, the Denver Art Museum in Denver and the Mint Museum in Charlotte. Andrew Hamilton also guided the research of the laboratories and shared generously the archival documents he had recovered with those involved in the project.

At the Denver Art Museum we are very much obliged to Margaret Young-Sánchez, who provided us with illustrations and information about the analysis of the Denver object. At the Denver Art Museum the analysis was coordinated by the senior objects conservator Gina Laurin and realized at the Laboratory of the Colorado School of Mines in Golden by Ed Raines, Bruce Geller, and Fred Fraiker. Jonathan Stuhlman, curator at the Mint Museum in Charlotte kindly checked the provenance of the golden corncob in their collection. To confirm the selling strategies of the art dealer Robert L. Stolper in different museums in Europe, Esther Tisa, in charge of the provenance research at the Museum Rietberg in Zurich, was so kind to provide us with transcriptions of the correspondence between the Museum Rietberg and Robert L. Stolper. The transcriptions were done by Pierre-Louis Blanchard. The research of Martin Berger on Robert L. Stolper and the unscrupulous art market in the 1960s made possible to fit the pieces of the puzzle together. Last but not least we are obliged to Paz Nuñez-Regueiro and Maria-Filomena Guerra who by their interest made this paper possible. Many thanks, to all of them.

1While conducting his research on Incan miniatures and their function within the Inca state for his PhD thesis, “Scale and the Incas”, Andrew Hamilton got aware of a representation of a corn plant with two cobs made of metal sheets at the Ethnologisches Museum in Berlin1. The relatively large size of the object (with a length of 25.7 cm and a width of 7x9 cm)2 is reminiscent of the descriptions found in Spanish chronicles of the plants and animals in natural size from the garden of the sun in Coricancha, the center of the Inca state in Cuzco, but none survived colonial times. In fact, there are only two similar objects of this kind reported worldwide, the one in Berlin (Fig. 1) and the other at the Denver Art Museum3(Fig. 2).

2They are unique because of their size, and their naturalistic representation. Hamilton initiated an extensive analysis. Several institutions contributed to this research: the Ethnologisches Museum and the laboratory of the Staatliche Museen zu Berlin, the Rathgen-Forschungslabor, dedicated to the analysis of cultural heritage objects and conservation science4, the Denver Art Museum in Denver, Colorado and The School of Mines in Golden, Colorado.

3Through the research it became clear that the authenticity of the objects had already been debated, after a picture of the Berlin piece was published in 1966 and in an English translation in 1967 of the “Daily Life in Ancient Peru”? (Disselhoff, 1966; 1967)5. The curator of the pre-Columbian collection at the Denver Art Museum, Robert Stroessner, became curious about the object in Berlin. Nevertheless he didn’t accept the arguments questioning the authenticity of the Denver piece. As he explains in a letter directed to Dieter Eisleb, curator at the Museum für Völkerkunde in Berlin:

  • 6 Letter from Robert J. Stroessner, Denver Colorado, USA, January 13th, 1969 to Dieter Eisleb, curato (...)

We have nearly an identical pair of “corncobs” in our collection, which is being questioned by American experts. The only explanation being “no known examples of this type have survived with collection history or excavation history”. Thus I am hoping we can prove both pieces are authentic6.

4The curator of the South American Archaeology at the Museum of Natural History in New York, Junius Bird, however, was quite convinced that the Berlin representation of corncobs was a fake. Bird emphasized mainly two aspects, which, to him, seemed to be indications for a falsification: the technique —the patina and artificial corrosion— and the botanical rendering.

5In the correspondence with the museum in Berlin, dated December 30th, 1968, Junius Bird also reminds us that at the end of the 1940s

  • 7 Letter from Junius B. Bird, Curator of South American Archaeology, December 30th, 1968 to Dieter Ei (...)

[…] some metal workers in Lima made a number of these in gold, silver and copper which were then sold as genuine antiquities. In addition to technical details, which revealed their modern origin (artificial patina, simulated breakage and corrosion, etc.), they were characterized by botanically inconsistent detail or errors of observation, which I am sure no pre-Spanish artisan would have committed. In most cases the ears are shown partially stripped of husks and with incorrect depiction of kernel row termination. Some also have far more rows of kernels than any corn ear ever had. In one instance, when a nearly complete corn plant was shown, the ear was at the top where the tassel should be7.

6There is obviously certain clumsiness in the representation of the plant (compare Fig. 3), as there are very sophisticated objects made of gold and silver sheets from the Chimú, from the north coast of Peru (Cordy-Collins, 1996). The provenance given by the art dealer, Robert L. Stolper, was in fact Chimú, a center for silversmiths since pre-Inca times. The object was bought by Hans Dietrich Disselhoff, head of the department of American archeology and director of the then Museum für Völkerkunde for 850 $, which equated 3,400 DM in 19618.

7In the first illustration published in “Alltag im alten Peru” 1966 by Hans Dietrich Disselhoff, the corncobs still show “gilded leaves” (Fig. 4). The reddish-golden color as well as the blackish patina nearly disappeared, probably after a cleaning, which is however not reported in the museum files. The Berlin piece today shows a metallic silver color with some blackish and greenish corrosion products on the exterior of the leaves and the stalk (Fig. 1)9. It remains unclear whether the yellowish/golden effect on the exterior leaves, caused by the application of a layer of lacquer, are due to the deposit conditions in the ground, or to an intentionally applied patina. The surface of the corncobs is darker, an effect which could be intentional or just due to the more difficult access for cleaning.

1. Analytical results

8The analysis of the material undertaken at the Rathgen-Forschungslabor showed that the alloy contained no gold (cf. Table 1), but different proportions of silver and copper. Surprisingly, the eight sheets, which compose the object, two for each cob, two forming the big leaves, one for the small leaf and one making up the stem show different alloys (cf. Fig. 5).

9The alloy and solder composition was probed by µXRF analysis with an Artax Spectrometer (Bruker) with about 100  µm spot size and a 30 W Mo-Tube. The Bruker MQuant fundamental parameter software was used for quantification. Despite the limitation of surface analysis of silver alloys, the surface µXRF showed some clear differences (Fig. 6). The large leaves and one part of the small cob have the same composition (60-70% Ag, and 28-38% Cu in weight), while the large cob and one half of the small cob are made by sheets with a higher silver content (88-91 Ag, and 5-7% Cu), the stem shows a third alloy (81 Ag, and 17% Cu in weight) (cf. Table 1).

10In the soldering spots a series of elements were detected in a low percentage like sulphur (S), iron (Fe), calcium (Ca), titanium (Ti), manganese (Mn), silicium (Si), and chlorine (Cl), which could originate from surface contamination. However, there is zinc (Zn) and copper (Cu) in higher amounts compared to the metal sheets.

11Zinc was only found in a higher percentage at the joint between the stem and the larger corncob: 7 wt% and 4.1 wt%, respectively10 (cf. Table 2). In other spots measured at the joints of the corn cobs, the percentage of zinc is lower than 1 wt% (0.3-0.5 wt%)11. Apparently zinc can appear occasionally in a low amount (up to 1.3 wt%) in Chimú and Inca silver objects and has been found to a lesser content in copper and copper alloy objects and have to be interpreted as accidental inclusion (cf. e.g. a survey of the collection at the Museo de América, Madrid) (Rovira Lloréns & Gómez Ramos, 1995: 21, cf. Table 1). To the knowledge of the authors there are no published analyses of Chimú and Inca solders for comparison. The analyses for the corncob solders up to 7 wt% Zn seems high for an element which was introduces as an accidental inclusion and might be an indication of a modern solder which would match with the reconstructed history of the object12.

12FTIR (Fourier transform infra-red analysis) and GC/MS (Gas chromatography-Mass spectrometry) was carried out on organic material. The FTIR analysis was carried out by a Typ Paragon 1000 PC (Perkin Elmer) in transmission by the use of a diamond cell. GCMS analyses were performed on a Perkin Elmer Clarus 500 (electron impact 70 eV, ion source temperature 230 °C, interface temperature 280 °C). The injection mode was splitless; the injector was kept at 280 °C, and the helium gas flow-rate was 1.2 mL/min. Chromatographic separation was performed on a Perkin Elmer Elite 5ms column (stationary phase: 5% phenyl, 95% methylpolysiloxane), with 0.25 mm internal diameter, 0.25 µm film thickness and 30 m length. GC conditions: initial temperature 100 °C, 0.5 min isothermal, 15 °C/min up to 150 °C, isothermal 1 min, 7 °C/min up to 300 °C, isothermal 20 min.

13There are residues of different modern polymers, identified by FT-IR, which were applied more recently: a two component adhesive based on epoxy resin, (sample P2) and a transparent lacquer (sample P6), which contained methyl methacrylate (MMA)13.

14The black substance at the bottom of the stem (sample P3) seems to be of organic nature. In the FT-IR analysis only weak bands in the C-H stretching region (2918, 2845 cm-1) and a very weak shoulder at 1734 cm1 indicate the presence of minor organic substances, the main component of the sample being of inorganic origin (quartz)14. GC/MS was used to verify if the sample could contain minor amounts of tar, as its appearance seemed to be indicating. Besides modern materials (e.g. plasticizer), few triterpenoid resin markers were found but none of the European reference materials tested (tars of birch bark, pine or bones) gave a satisfactorily positive match for a tar or pitch. A similarity was found with tar made of bone material, which nevertheless would need to be systematically studied in order to be correctly interpreted. An unequivocal identification might be possible in the future if compared with the corresponding reference samples from South America could be achieved.

2. The art dealers

15Both pieces, the one in Berlin as well as the one in Denver, are unique and similar in shape, size and the composition of the alloys (cf. Table 2, 3). As there are no similar objects known from archaeological contexts, it is quite possible that both of them came from the same workshop in Lima as Junius Bird proposed.

16We only know that the Denver Art Museum bought their object from the Julius Carlebach gallery15, and Berlin bought theirs from Robert L. Stolper. The connection between the art dealers is easily explainable, as Robert Stolper, once he moved from Los Angeles to New York in 1961, installed his gallery at 1040 Madison Ave., a two minute walk around the corner from Carlebach’s at East 80th Street, close to the Metropolitan Museum of Art.

17Unfortunately, it is not yet possible to trace the provenances further back than to the galleries at the Upper East Side in New York. Nevertheless, it is possible that the first owner of both objects had been Julius Carlebach, who might have sold one of the representations of corncobs to Stolper, once Stolper arrived in New York. By this manner Stolper was able to offer it to his circle of clients in Europe, which did not overlap with Carlebach’s, who mainly sold within the USA16. Julius Carlebach had gone into exile from Berlin to New York and was well known as the main provider of “primitive art” to Georg Gustav Heye, the founder of the Museum of the American Indian in New York17. Stolper however expanded in Europe where since the 1960s he had altering branches in different European cities, in Saint-Légier (Switzerland), Amsterdam, London, and Munich18.

18The 1960s were heydays on the art market. Due to the economic highpoint combined with the awareness of damages suffered in Second World War, German museums spend a lot to compensate the losses, either those in objects as well as those in reputation and relationships with the international community. The construction of a new building for the Museum für Völkerkunde in Berlin-Dahlem, which opened in 1970, was the background for “completing” the collections (Westphal-Hellbusch, 1973). From Stolper the Museum für Völkerkunde bought 279 ethnographic objects from different parts of the world: Africa, India, south East Asia and Australia; over half —195 objects— originate from the Americas. Between 1960 and 1983, 79 pre-Columbian pieces were bought for the sum of 423.245 DM, with several acquisitions every year. A ceremonial knife (tumi) from Lambayeque (Peru) was bought from the Stolper Gallery in 1966 for the amount of 54.000 DM (Fig. 7).

19As a selling technique Robert Stolper deposited objects he wanted to be purchased in one of the museums he was related to and waited until the annual budget was released and the objects could be bought. In the meantime, he maintained an active personal correspondence with the respective museums curators19. In some cases the purchased objects were even exchanged by the museums with objects taken from the historical collections.

20However, not all the artworks Stolper offered were trustworthy. One of the early acquisitions from the Stolper Gallery at the museum in Berlin, a stucco head supposedly related to Palenque, turned out to be a fake (Gaida, 2014).

  • 20 Two more stucco heads offered to the Etnografisk Samling in Copenhagen, were declined.

21The very euphoric assessment of the stucco head —it was compared to the bust of Nefertiti— soon was questioned by Gordon Ekholm, curator for Mexico and Central America at the Museum of Natural History in New York20. At the International Congress of Americanists in Spain 1964, Dieter Eisleb, then curator at the Department of American Archaeology and Gordon Ekholm agreed upon the examination of the stucco head (Fig. 8). The analysis made by Ekholm showed a high amount of calcium sulphate in the stucco head (not usual in Palenque stucco samples), and even a fresh hair of a domesticated pig. When confronted with the result, Stolper immediately offered a replacement for the fake. The curators in Berlin chose a Huaxtec Stela in exchange and maintained the relationship for 20 more years.

22This is not the only case where Robert Stolper was involved in deals of artworks, which turned out to be fakes. A particularly brazen case is the “Mesoamerican human skull decorated with turquoise mosaic” sold by Stolper to the National Museum of Ethnology in Leiden (the Netherlands). Martin Berger found out that there were ten similar pieces in different museums and private collections (Berger, 2013). The skull at the Museum in Leiden was also bought in the 1960s, nearly at the same time as the Berlin silver corncobs, and also appealed to curators because of its uniqueness. By that time, in 1963, there were little archaeological contexts available (with exception of tomb 7 at Monte Alban (Caso, 1932)). Nevertheless several scholars soon concluded that these skulls might not be complete fakes, but a modern combination of pre-Columbian elements21. The analysis carried out by the Centre de Recherche et de Restauration des Musées de France in Paris in 2011 and 2012 confirmed the hypothesis, the skulls being composites, made out of pre-Columbian elements put together in a way that, as Berger puts it, they “fit the style”22.

23As far as the representation of corncobs is concerned, it might be a similar type of fake. Putting together the pieces of the puzzle there is (1) the iconography, which has not been reported in any archaeological context, and (2) the different compositions of the alloys (cf. Table 1), which could be a hint to the reuse of pre-Columbian silver sheets from originally different contexts. Particularly cups (aquillas) made of silver sheets, often found in bad conditions in archaeological contexts, could easily be reshaped and assembled. This would also explain (3) the different modern glues and “solders” containing a higher percentage of Zinc in the joints (cf. Table 2). With the alleged provenance “Chimú” it would —as Martin Berger proposed for the mosaic sculls— “fit the style”, here of pre-Columbian metalwork from the North coast of Peru in the Late Intermediate Period and Late Horizon (1200-1532 AD).

  • 23 Cf. Radnóti, 1999; Bruhns & Kelker, 2010; Kelker & Bruhns, 2010; Jones, 1992; Dagen & Murphy, 2013.

24On the strategies of placing so-called “primitive art” on the art market after Second World War little has been studied yet23. The criminal energy inverted by some of the art dealers and the willingness of collectors and museums curators to ignore suspicions in favor of unique artwork for their collections is a field highly worthy of our attention.

3 A third representation of a corn cob hosted at the Mint Museum, Charlotte (North Carolina, USA) is different in shape and material and will not be referred to in this paper. We want to thank Jonathan Stuhlman for the research he did on the provenance: “The corn cob effigy had been on loan to us since the 1980s and was formally donated in 2008. It came from a private collection; the collector lived nearby but also spent a great deal of time in Italy and London; I did not see anything in the files indicating that we knew more about its provenance”. Email Jonathan Stuhlman to Manuela Fischer, 31. 8. 2015. Available in http://www.mintmuseum.org/?open_collection=%2Fresources%2Fcollection-database%2Fitem%2F2008.81.7%2Fmaize-cob-effigy%2F Inventory no. 2008.81.7, gift of William and Mary Barnes. The place where the object was created is indicated with: “Southern Highlands”.

12 The alloy of copper and zinc (brass) is introduced to the Americas in colonial times. Nevertheless zinc can appear in high percentages (up to 28%) in some pre-Columbian bronzes, e.g. in early axes from Northwestern Argentina. A simultaneous melting of copper and zinc is not possible due to the different melting points (González, 2004: 142-143). No further data on pre-Columbian silver objects containing such high Zn contents is yet available.

22 The skull was suggested to be pre-Columbian from the Mixtec area, and the turquoises and shells typical for the Post classic period. The concretions (hydroxylapatite) at some of the shell inlays nevertheless only attach if lying for a long time in the ground. The attachment of one of the mosaics was made with the usual pre-Columbian glue (copal, bee wax, etc.). All of them showed modern glues: modern household glue (Duco cement) at the Dumbarton Oaks piece, or shellac originating from Asia (at the skull in Marseille) (Berger, 2013: 28).
