The article deals with the problem of the Russian and European schools of stone carving interaction through the prism of orders fulfilled for Nikolay N. Demidov by Parisian workshops. The author analyzes a unique set of works presenting results of their attribution and study, focusing on the activity of the early 19th century French stone carvers and mosaicists with reference to the 19th -early 20th centuries foreign sources hitherto unstudied by Russian scholars. The author provides the first publication of some archival data on the biography of Aleksandr I. Lyutin, head of Yekaterinburg lapidary factory, drawing a conclusion on the character of interaction between European stone carvers and N. N. Demidov.
