Luc-Olivier Merson (1846–1920) was a celebrated French painter, illustrator, and designer, known for his work in the Symbolist style. Born in Paris into an artistic family, he studied at the École des Beaux-Arts under Gustave Chassevent and Isidore Pils. Merson gained early recognition for his historical and religious paintings, often marked by meticulous detail and symbolic depth. His breakthrough came in 1869 when he won the prestigious Prix de Rome for his painting *The Soldier of Marathon*.
Merson’s work is characterized by its poetic and mystical qualities, blending realism with fantastical elements. He often depicted themes drawn from mythology, history, and Christianity, with famous works like *Rest on the Flight into Egypt* exemplifying his ethereal style. In addition to painting, Merson contributed to various mediums, including stained glass design, book illustrations, and postage stamps, most notably designing France’s *Marianne* stamp.
He was also an influential teacher at the École des Beaux-Arts, where he mentored a generation of artists. Although his fame waned with the rise of modernism, Merson's unique blend of symbolism and classical techniques has left an enduring legacy in French art, making him an important figure in the late 19th and early 20th centuries.
