The Natufian culture existed from 12,500 to 9,500 BCE in the Levant, a region in the Eastern Mediterranean. The Natufians were among the first humans to abandon the nomadic lifestyle and settle in permanent communities, including the construction of buildings with stone foundations. They decorated graves with flowers, held ceremonial meals before their funerals, and - as a new study from the University of Haifa now shows - they also created massive mortars that were used to pound food at their burial ceremonies.
     "Their communal burial and commemorative ceremonies played an important role in enhancing the sense of affiliation and cohesion among the members of the community," explain Dr. Danny Rosenberg and Prof. Dani Nadel, from the Zinman Institute of archaeology, University of Haifa, who undertook the study.
     Over the years, numerous tools have been found at Natufian residential and burial sites, but relatively little attention has been paid to one of the most remarkable types of tools: large boulder mortars, some of which are almost a meter high and weight 100 kg. "These are the largest stone artifacts that were hewn during this period in the Middle East, and indeed they are much larger than most of the stone objects that were hewn here in much later periods," Dr. Rosenberg explains.
     Despite this, no one undertook an overall examination of the phenomenon of the boulders, so the two researchers investigated most of the boulders of this type that have been found in the Middle East. They discovered that almost all the boulders were found in burial sites or in contexts relating to burial. Some of the objects were found buried in the ground, with only their upper edge visible. "The size and weight of the boulders shows that they were not intended to be mobile. The fact that some of them were buried suggests that they were supposed to remain in place as part of the 'furniture' of the burial site, or in the burial context itself. This point emphasizes that they were not created for everyday eating purposes, but formed an integral part of the ceremonies and occurrences in the areas in which the Natufians buried their dead."
     The researchers argue that the giant boulders can be seen as part of a broader Natufian phenomenon connecting different areas through a single system of ceremonies and beliefs. They concluded that the boulders also played a central role in these ceremonies, seeking to reinforce collective cohesion and identity. The food ground by the boulders played a social or ceremonial role, similar to familiar contemporary functions. The pounding on or in the boulders could be heard at a great distance, and may have served to announce the holding or the beginning of the burial ceremony, thereby informing the members of adjacent communities that an important ceremony was taking place - much like church bells.
