Karl Maria Diez

~ 1883 - 1941

Karl Maria Diez (often abbreviated C.M. Diez) was an Austrian‑German illustrator whose work is closely associated with the erotic strand of Art Nouveau at the turn of the twentieth century. He is best remembered for providing the elaborate title plate and a series of sensual vignettes for the first complete German translation of the Marquis de Sade’s Les 120 Journées de Sodome (published privately in Leipzig in 1908). The book’s decorative programme with gold‑stamped leather binding and ornamental initials completed with the distinctive, flowing line work of Diez was executed in the workshop of Rosenburg and remains a landmark of clandestine erotic publishing.

Beyond the Sade edition, Diez supplied Art Nouveau‑style decorations and bindings for the German edition of Julian Robinson’s Gynecocracy (translated by E. von Berini‑Bell), another work that entered the canon of early‑modern erotic literature. His illustrations are characterised by elegant, sinuous contours, stylised female figures and a refined use of ornament that echo the broader currents of Jugendstil while retaining a distinctly erotic charge.

Very little is known about Diez’s personal life: birth and death dates, training, or broader oeuvre have not been documented in mainstream sources. Contemporary auction listings (e.g., AbeBooks) continue to reference his name in connection with the 1908 Leipzig private print, confirming his role as the book‑designer for that historic edition.
Diez’s legacy therefore rests almost entirely on these few, highly prized publications, which today are valued by collectors of both Art Nouveau graphics and rare erotic literature.

Karl Maria Diez's work as an illustrator and artist was deeply rooted in Jugendstil, the German expression of Art Nouveau, which flourished in the late 19th and early 20th centuries. Jugendstil, named after the Munich-based magazine Jugend (founded in 1896), emphasized organic forms, flowing lines, and a rejection of rigid academic art in favor of decorative, aesthetic innovation. Diez's illustrations, particularly for erotic literature like The 120 Days of Sodom and Gynecocracy, reflect these influences through their stylized elegance, intricate detailing, and sensual motifs.

I have added one colored artwork that shows the same scene as used in Die Geschichte der körperlichen und der seelischen Erlebnisse des Julian Robinson. It is a colored artwork not in the style of Diez, it might be from a different artist but to this day I could not find any lead on the artwork.
