Xavier de Langlais (1906–1975) was a French painter, illustrator, and writer deeply connected to Breton culture. He focused on religious and historical subjects, creating murals, altarpieces, and illustrations that combined classical techniques with Celtic-inspired themes. His art emphasized careful drawing, symbolism, and spiritual atmosphere, often commissioned for churches and cultural institutions in Brittany. Beyond painting, de Langlais was a teacher and author, writing manuals on traditional techniques like egg tempera and pigment preparation. His work preserved both Breton cultural identity and traditional artistic craftsmanship, making him a key figure in 20th-century regional French art.
