## About Mariette Lydis

Mariette Lydis was born Marietta Ronsperger in 1887 near Vienna and became a versatile Austrian painter, illustrator, printmaker, and draftsperson. She adopted the surname Lydis after her 1918 marriage to Jean Lydis. Active in France for much of her interwar career, she developed a reputation for evocative book illustrations alongside her painting and printmaking practice. In 1940 Lydis relocated to Buenos Aires, where she lived with her partner Erica Marx until her death in 1970. She is recognized for living openly as bisexual at a time when few public figures did so. Her work enters institutional collections, including the Museum of Modern Art in New York, and is documented by the RKD, Getty ULAN, VIAF, and the Library of Congress. Collectors most frequently encounter her through illustrated editions, etchings, and paintings that appear at international auction.

## Common works and media

Oil paintings on canvas and panel, watercolors, etchings, lithographs, book illustrations, and drawings. Figurative subjects, portraiture, and literary-themed compositions appear frequently. Her illustrated limited-edition books are especially common in auction and appraisal contexts, alongside original prints and works on paper.

## Market and appraisal context

With close to 200 documented auction appearances, Mariette Lydis's work circulates regularly on the secondary market. Her output spans oil paintings, watercolors, etchings, lithographs, and illustrated books. Collectors should distinguish between unique paintings and drawings, which tend to carry higher values, and reproductive prints or book illustrations, which are more common at auction. Provenance connecting a work to her French or Argentine periods can provide useful context. Condition, edition size for prints, and whether a piece is hand-signed are standard valuation factors. Public auction records from major houses remain the most reliable price benchmarks for her market.
