Contemporary Lithuania, an area of the Balt cultures, is the northernmost region where burials, dated from the late second to the late seventh century ad, have been found with selected parts or whole bodies of horses. This study presents new information about these burials based on a multidisciplinary—archaeological, zooarchaeological, and chronological—approach. Our aim is to reconstruct the funeral rites and the human-horse relationships in Lithuania from the late second to the late seventh centuries ad, to refine the chronology of the horse burials in the region, and to use the new zooarchaeological data for more detailed studies of mortuary practices.
