(Fabric weaving manuscript).- Felix, M. & J. Mercier. Cahier de Théorie 4e Année 3e. N.p. (Lyon?) n.d. (circa 1895). 
Though we know little about the person who composed it (“J. Mercier,” seemingly a student in the 4th-year class of one “Professeur M. Felix”), Cahier de Théorie 4e Année 3e offers a rich window into the world of industrial fabric design in turn-of-the-century Lyon—once a world capital of silk production.
The folio-size graph-paper notebook contains page after page of sketches and patterns for elegant fabrics accompanied by 74 fabric swatches and the student-designer’s painstaking notes in a careful hand.
To an expert in the history of textile design these pages would no doubt speak volumes about the industrialization of the loom and the translation of warp-and-weft handwork into modern machine processes. To the untrained eye (or at least my own) the remarkably beautiful designs also suggest complex musical compositions.
