François "Prosper" Colas (1842–1919) was a renowned French archetier, also known as a bow maker, who established his craft in Mirecourt, France. Having been born in Goincourt in 1842, Colas underwent a local apprenticeship that greatly shaped his early work, which bore the influence of the late Dominique Peccatte school. Upon relocating to Paris around 1871, he likely crossed paths with Jean-Baptiste Vuillaume and subsequently worked under him, a period during which the first bows bearing his brand emerged, reflecting Vuillaume's distinct style. Prosper Colas's extensive career involved collaborations with various makers, resulting in a prolific output of high-quality bows, particularly during the early 20th century. His more modest productions were marked with the stamp "P.C." Additionally, instruments with Colas's label were retailed alongside those crafted by prominent Mirecourt workshops of his era, such as Jérôme Thibouville-Lamy and Marc Laberte. Following his passing in 1919, his business was succeeded by Ferret-Marcotte. References: Roda, Joseph (1959). Bows for Musical Instruments. Chicago: W. Lewis. OCLC 906667. Vatelot, Étienne (1976).
