Short answers, pulled from the story.
The Oseberg ship was discovered in a large burial mound at the Oseberg farm near Tønsberg in Vestfold county, Norway. It was excavated between 1904 and 1905 by Swedish archaeologist Gabriel Gustafson and Norwegian archaeologist Haakon Shetelig.
Scientific dating indicates the Oseberg ship was buried no earlier than 834, with the grave chamber's timbers specifically dated by dendrochronology to the autumn of 834. Certain structural parts of the ship date from as early as 800, and some components may be even older.
Two women were buried in the Oseberg ship. One was probably around 80 years old and had arthritis as well as Morgagni's syndrome. The other was aged approximately 50-55 based on tooth-root analysis. The identity of the higher-ranking woman is unknown, though she has been suggested to be Queen Asa of the Yngling clan, mother of Halfdan the Black.
The Oseberg burial contained four elaborately decorated sleighs, a richly carved four-wheel wooden cart (the only complete Viking Age cart found so far), bed-posts, wooden chests, agricultural and household tools, woolen garments, imported silks, narrow tapestries, and the so-called Buddha bucket. The skeletons of 14 horses, an ox, and three dogs were also present.
The Buddha bucket, known in Norwegian as Buddha-bøtte, is a pail made from yew wood held together with brass strips. Its handle features two small figures sitting with crossed legs, comparable to depictions of the Buddha in the lotus posture. Scholars link the patterned enamel on the handle more closely to Insular art traditions from Ireland, specifically figures found in Gospel books like the Book of Durrow.
The Saga Oseberg reconstruction, launched from Tønsberg on the 20th of June 2012, proved the design was genuinely seaworthy. In March 2014 it was sailed on the open sea toward Faerder and achieved 10 knots under full sail, matching the estimated top speed of the original. The original Oseberg ship also has 15 pairs of oar openings for up to 30 rowers and a sail area of approximately 90 square metres.
