ENWe report on the scientific and historical study of a mummy associated with an Egyptian coffin once belonging to Count Aleksander Branicki, an important Polish collector who took part in two private expeditions to Egypt during the mid-nineteenth century. Recently the object was submitted for radiological investigation, as well as radiocarbon dating, in order to obtain a clearer picture of the biohistory and chronology of the body contained within the coffin. Furthermore, new documentary evidence was recovered that illustrates the colorful journey of the artifact and its contents from Egypt to Europe. [From the publication]
