A total of 22 internationally renowned experts from nine countries present the miniature portrait from different perspectives, discussing the private use of miniatures, special depictions, and messages conveyed by miniatures. Significant but little-known museum collections are introduced alongside insightful information about the living conditions of the artists active at the time. Lastly, aspects regarding the production techniques for miniatures are examined. This fourth volume publishes the presentations given at the 2024 conference held by the Tansey Miniatures Foundation. Interested individuals from all over the world come together in Celle every two to three years at these conventions on the portrait miniature to discuss this special genre of portrait painting.
