A female Viking warrior confirmed by genomics
نویسندگان
چکیده
OBJECTIVES The objective of this study has been to confirm the sex and the affinity of an individual buried in a well-furnished warrior grave (Bj 581) in the Viking Age town of Birka, Sweden. Previously, based on the material and historical records, the male sex has been associated with the gender of the warrior and such was the case with Bj 581. An earlier osteological classification of the individual as female was considered controversial in a historical and archaeological context. A genomic confirmation of the biological sex of the individual was considered necessary to solve the issue. MATERIALS AND METHODS Genome-wide sequence data was generated in order to confirm the biological sex, to support skeletal integrity, and to investigate the genetic relationship of the individual to ancient individuals as well as modern-day groups. Additionally, a strontium isotope analysis was conducted to highlight the mobility of the individual. RESULTS The genomic results revealed the lack of a Y-chromosome and thus a female biological sex, and the mtDNA analyses support a single-individual origin of sampled elements. The genetic affinity is close to present-day North Europeans, and within Sweden to the southern and south-central region. Nevertheless, the Sr values are not conclusive as to whether she was of local or nonlocal origin. DISCUSSION The identification of a female Viking warrior provides a unique insight into the Viking society, social constructions, and exceptions to the norm in the Viking time-period. The results call for caution against generalizations regarding social orders in past societies.

Egill Skallagrímsson, a tenth-century Viking, was a colourful warrior poet and an early anti-hero. The thickness and strength of his skull and his very ugly facial features with a prominent mandible have suggested to some authorities that Egill suffered from Paget's disease of bone. However, Paget's bone, while thickened, lacks structural integrity, infrequently involves the mandible and is pro...
