The image is from a series about Penthesilea, the mythic queen of the Amazons, as recounted by Heinrich von Kleist, a German Romantic writer whose work Raoul Ubac read in his youth. To represent the queen and her consort, Ubac carefully lit and posed his wife, Agi, with a friend, and he solarized the resulting images to partially annihilate their forms. Ubac was deft with his darkroom manipulations: to create this image he progressed through four steps of montage, repeating solarizations on each of them in turn. He pieced in additional nudes and objects—different images of Agi and her friend brandishing staves, coils of rope, and stones—with extra shots of Agi’s curly hair. The work was then rephotographed and solarized during processing, then combined with other images in further iterations with still more elements in steps that are almost invisible in the finished image, though perceptible in the fine gradation of tones in the darkest passages.  Thus Ubac metamorphosed a few negatives of real people and things into larger rhythmic groupings of as many as twelve figures displayed horizontally, as in a frieze.
The series recalls ancient Greek carvings of Amazons, whose naked flesh and coils of hair emerge from the shadowed recesses of sarcophagi; here these symbols of strong sexual and aggressive drives seem to arise from the archaic unconscious. Photography was useful for the Surrealists because of its unique relationship with reality: its truthful depiction contains its potential deformation (due to the plasticity of the photographic negative/positive process). The Penthesilea groupings perfectly demonstrated this duality, so much so that they were chosen by the Surrealist-in-chief, André Breton, to accompany one of his poetic texts in Minotaure, an important Surrealist magazine that also featured charged and highly evocative images by Man Ray and Brassaï. 
This unusually large, exhibition-scale photograph was printed on Agfa Brovira double-weight paper by Ubac probably a few years after World War II, when bigger photographic papers once again became available after wartime shortage. Brovira paper was one of the longest-lived products made by Agfa. The product logo appears on the verso of this sheet in a font and style suggesting that the paper was manufactured in the 1940s to mid-1950s. The presence of titanium in the paper, detected through X-ray fluorescence analysis, also suggests a late date for the print, since manufacturers began to use titanium as a paper filler in the 1950s. The paper’s very matte surface emphasizes the flat gray tone that seems to steal over the nudes like sediment settling, solidifying them into fossils. Despite this or perhaps in part because of it, the malevolent eroticism generated by these strangely metamorphic figures remains unsettling and potent.

This work was determined to be a gelatin silver print via X-ray fluorescence (XRF) spectrometry.
The following elements have been positively identified in the work, through XRF readings taken from its recto and verso (or from the mount, where the verso was not accessible):
- Recto: P, S, Ca, Zn, Sr, Ag, Ba
- Verso: Al, P, S, Ca, Ti, Zn, Sr, Ba
The graphs below show XRF spectra for three areas on the print: two of the recto—from areas of maximum and minimum image density (Dmax and Dmin)—and one of the verso or mount. The background spectrum represents the contribution of the XRF instrument itself. The first graph shows elements identified through the presence of their characteristic peaks in the lower energy range (0 to 8 keV). The second graph shows elements identified through the presence of their characteristic peaks in the higher energy range (8 to 40 keV).
