RESUMO
OBJECTIVES: Intentional cranial modification (ICM) was a long-established tradition used to reshape the head. Unfortunately, motivation of the act is unclear. It has been found in recent and contemporary human populations throughout the Old and New Worlds, yet the drawback of the quest into the origin, diffusion, and meanings of ICM is the lack of early materials for scientific examination. This study reports the discovery of ICM from the Neolithic Houtaomuga Site in Northeast China and the importance in deepening our knowledge of this intriguing tradition. MATERIALS AND METHODS: Twenty-five skeletons unearthed from the Neolithic cultural Phases 1-4 in the Houtaomuga Site were visually screened for ICM features. Cranial measurements were conducted to quantify the degree of variation in the modified skulls and typical ones were computer tomography (CT) scanned to obtain a diploë structure and 3D model. RESULTS: Eleven skulls carrying signs of ICM from both sexes varying in age from juveniles to full adults were identified ranging from 12,000 BP to 5,000 BP. Three types of modification patterns were observed and most of them were of typical fronto-occipital modification pattern. In particular, there were remarkable variations in the curvature of the crania along the sagittal direction. DISCUSSION: Overall, the antiquity as well as the cultural and genetic continuity of the population in Houtaomuga Site demonstrated the earliest confirmed ICM cases from the easternmost Old World, and the longest in situ duration of ICM practice at one single Neolithic site. This circumstance largely contributes to our understanding of the origins and distribution of ICM in Eurasia and the American continent.

OBJECTIVES: The arrival of the Huns into Europe in the fourth century AD increased the occurrence of intentional cranial modification among European nomads. It has been postulated that the Huns used a two-bandage cranial binding technique to differentiate themselves from surrounding nomadic groups, including those from Georgia. This study examines this hypothesis by comparing Migration Period (4th to 7th century AD) juvenile crania, which retain strong impressions of bindings, with adult modified crania from Hungary and Georgia. MATERIALS AND METHODS: Twelve surface landmarks and 251 semi-landmarks were used to study ontogenetic trajectories in 9 juvenile and 16 adult modified skulls from 8 Hungarian sites and 21 adult skulls from two Georgian sites. Generalized Procrustes analysis, linear regression of Procrutes distance on dental age and log centroid size, and warping the principal components (PCs) in shape space helped to identify cranial shape changes. RESULTS: The PCs provide significant separation of the juvenile and adult groups from Georgia and Hungary. Variation in modified cranial shape was limited in Hungary compared to Georgia. There was stronger correlation between juvenile and adult modified cranial shape in Hungary than in Georgia. Warping along the first axis reveals the trajectory from marked flattening of the frontal and occipital regions in juveniles to diminished flattening in the same regions in adult crania, corresponding with one binding. Another depression extending from the post-bregmatic region to the temporal region, similarly strong in juveniles but diminishing in adults, marks the second binding. DISCUSSION: Hungarian crania were modified with two bindings with limited shape variation, whereas the Georgian crania had greater variation in shape being also modified with antero-posterior bindings. The findings from this study alongside contemporary historical sources help to understand the role of intentional cranial modification as a mark of social identity among nomads in the Migration Period of Europe.
