Seiz Breur (Breton for "The Seven Brothers") was an artistic movement that originated in Brittany, France, and was active between 1923 and 1947. Initiated by the artist Jeanne Malivel, a professor at the Rennes School of Fine Arts, the movement sought to create a modern Breton aesthetic by synthesizing contemporary European art trends, such as those of the Arts and Crafts movement and the Bauhaus, with the region's distinct cultural and linguistic heritage.
Seiz Breur artists produced a wide array of works, encompassing embroidered banners, faience figurines, liturgical objects, and everyday items such as books, postcards, stamps, calendars, jewelry, furniture, and posters. They encouraged the use of modern materials like concrete and innovative techniques like photocollage and cinema. Characteristic motifs in their art included saw-tooth patterns, spirals, triskeles, hermines, palettes, and peacock feathers, often rendered with a modern aesthetic influenced by Art Deco.
Regencycore is an interpretation of the Regency aesthetic originating in the early 2020s. Rather than it being an accurate recreation of the Regency historical period, this fashion style and literary genre utilizes a more modern or over-the-top tone that incorporates Rococo/Baroque and Royalcore aesthetics and literary tropes that would not be true to Regency society.
