The First Monumental Burials in the Fifth Millennium BC: Unresolved Questions about the Emergence of the 'Passy Phenomenon'

Funerary monuments appeared shortly after the arrival of the first farmers along the Atlantic Coast of continental Europe, during the first half of the fifth millennium. These enormous constructions, belonging to the 'Passy' phenomenon, can measure over 350 m in length and were erected to commemorate high-status individuals. No funerary evidence from the previous period hints at the emergence of these monuments. They do not exhibit any geographical continuity, originating from different cultural substrates. Nevertheless, these structures are characterized by the repetition of specific traits, including their layout and their spatial articulation, as well as a high degree of gender segregation and a focus on hunting or archery. This convergence reflects a well-established social structure and ideology, shared between communities. Moreover, it implies that the descendants of the two main cultures responsible for the spread of agriculture in Europe, the Linearbandkeramik (LBK) and the Impresso-Cardial, which met at the end of the continent and which absorbed the descendants of the last hunter-gatherers, generated a new value system, and likely a new religious universe. While the funerary monumentality that appeared alongside the Passy phenomenon continued in the form of megaliths, the system eventually collapsed after a few centuries-which was to be expected, given its extreme character.
