Abstract: This research reveals the basic principles of the mourning decorations created for the burial of Peter the Great, and traces their fate in the Russian imperial sorrowful processions throughout the XVIII century. Decorative arrangement of state ceremonies is viewed in the context of the panegyric culture of that time. Ceremonial decoration was of temporary (occasional) nature and have been scarcely preserved; other than certain artifacts. The research is based on examination of a wide variety of written and graphic sources that allow reconstructing the image of funeral processions of that time. It is demonstrated that that in preparation for the funerals of Peter the Great, were developed certain patterns of mourning decoration preserved throughout the entire XVIII century. The principles of decorative arrangement of Russian imperial sorrowful processions were based on the European examples, and in many ways by inviting the foreign inventors and masters. The system of creation of mourning ensembles (as well as festive) obeyed the general laws inherent to the court ceremonial culture of Modern Age. The artistic solution of memorial halls and hearses corresponded to the stylistic evolution of art. The author introduces new materials and previously unknown facts into the scientific discourse, as well as clarifies the questions of terminology.
