Jean-Louis de Marne, Jean-Louis Demarnette, Marnette

Jean-Louis Demarne, also recorded as Jean-Louis de Marne, Demarnette, or Marnette, was a French painter and engraver born in Brussels in 1752. He died on 24 March 1829 at Batignolles. Authority records from Wikidata, Getty ULAN, and the Bibliothèque nationale de France help connect the documented spelling variants to the same historical artist. The collected biographical sources identify him with genre painting and engraving, so collectors may encounter his name in connection with paintings as well as graphic works. Because his surname appears in several forms, dependable entity matching requires comparing a signature or attribution with documented variants instead of treating every spelling as a separate maker. Appraisily also associates this entity with a body of auction records, making identity normalization important when selecting comparable lots. The available evidence is stronger on identity than on training, chronology, institutional history, or named series, so those areas remain unstated.

PaintingEngravingGenre scenes

Common works and media

The collected sources support two broad kinds of work associated with Jean-Louis Demarne: paintings and engravings. They also describe him as a genre painter, making scenes of everyday life the clearest documented subject context in this source pack. No named series, edition structure, or more detailed subject classification is sufficiently documented here.

Market and appraisal context

An appraisal should first distinguish between Demarne's paintings and engravings, since the source pack supports both work types. The recorded name variants—Demarne, de Marne, Demarnette, and Marnette—also matter when searching catalogues and selecting comparable auction records. Relevant comparisons should consider the stated attribution, work type, sale date, and realized price rather than combining every result attached to a similar spelling. Appraisily's page provides an auction-record signal, but the collected sources do not include detailed major-auction-house lot descriptions or enough evidence for price trends, scarcity claims, or a dependable value range. Any conclusion about a particular object therefore requires object-specific research and appropriately matched public sales.

Auction categories and appraisal factors

Common auction categories

  • Paintings
  • Engravings and other graphic works

Value drivers

  1. Work type and medium, particularly whether the object is a painting or an engraving
  2. Attribution and entity matching across the documented Demarne, de Marne, Demarnette, and Marnette name variants
  3. Comparison with relevant public auction records, including sale dates and realized prices when available

Appraisal caveats

  • The collected source pack contains an Appraisily auction-record signal but no detailed major-auction-house lot pages, so it does not support price-trend or price-range claims.
  • The sources establish broad work types and genre context but do not document named series or a detailed subject taxonomy.
  • Name variants should be normalized for research, but a shared name alone does not establish authorship or attribution for an individual object.
