Sacred character of foster-brotherhood—Ceremony of becoming foster-brothers—The oath—Joint ownership of property—Dissolution of the tie rare—Love between foster-children and foster-parents—Obligations.

Perhaps the most beautiful, touching, and unselfish trait in the character of man of which we have any record is the ancient custom of foster-brotherhood, which prevailed among the earlier Norse tribes. This relation between two men was of a most sacred and binding character, and was not even severed by the death of one.

Foster-brothers were those who in their youth had been brought up together—the sons of the fosterer and he who was fostered by him—or men who had fought against each other. Many examples are given of valiant men who fought against each other admiring each other’s bravery and becoming foster-brothers, pledging themselves by an oath, attended with the ceremony of letting their blood flow together on the earth.

After this impressive ceremony the men considered themselves bound to each other for life—to be unselfish and true to share the same danger, and avenge each other’s death; in fact their motto was, “One and the same fate may come over us.”

“In old times it had been the custom of valiant men, who made the agreement between themselves, that the one who lived the longest should avenge the other; that they should walk under three jardarmen,[[88]] and that was their oath (equivalent to an oath). It was done thus: Three long slices of turf were to be cut up; their ends were to be fastened in the ground, and the loops raised so high that a man could go under them. This Thorgeir (Hávarsson) and Thormód (Bersason) did” (Fostbrædra Saga, 1).[[89]]

Gisli was at a Thing with his brother-in-law Vestein. There were also a Godi named Thorgrim, and Gisli’s brother Thorkel. Gisli said:

“‘I think it right that we should bind our friendship still closer than before, and we four swear one another foster-brotherhood.’ To this they consented, and went on Eyrarhvolsoddi (point or tongue of land), and there cut from the ground a loop of turf, both ends being attached to the ground, and under this placed a spear inlaid with ornaments, so long that a man could reach with his hand to the spear-nail (i.e., the nail fastening the spear-point to the handle). Under this were to go the four, Thorgrim, Gisli, Thorkel, and Véstein. They then drew blood from themselves, and let it run together into the mould, which had been cut under the loop of turf, and mixed together the earth and the blood; thereupon they all fell on their knees and swore an oath that each should avenge the other like a brother, and called all the gods as witnesses. They all shook hands” (Gisli Súrsson’s Saga, p. 11).[[90]]

When Angantýr and Beli were fighting, the latter became exhausted, and would have been killed by the former but for Thorstein, who came forward, and said:

“‘I think it right, Angantýr, that you should stop fighting, for I see that Beli is exhausted, and I will not be so mean as to help him against thee, but if thou becomest his slayer I will challenge thee to a hólmganga, and I think we are not less unequal than thou and Beli; I would kill thee in that hólmganga, and it would be a great loss if both of you were to die. Now will I offer thee this condition, if thou givest Beli his life, that we swear each other foster-brotherhood.’ Angantýr said: ‘It seems to me a fair offer, that I become the foster-brother of Beli, but it is a great boon for me to become thy foster-brother.’ This was then agreed upon. They let blood flow from the hollow of their hands, and went under a sod, and swore oaths that each one should avenge the other, if any one of them was slain with weapons” (Thorstein Vikingsson, c. 21).

It was usual to swear an oath that whoever survived his foster-brother should avenge him by weapons if he died, not sparing even his own relatives.
