Hlautteinar, the Blood Twigs

Two of the fullest surviving descriptions of pre-Christian Norse sacrificial practice, in Eyrbyggja Saga and in Snorri Sturluson's Hakonar saga Goda within Heimskringla, describe a blot, a sacrificial feast held in honour of the gods, as involving both a bowl, the hlautbolli, and a bundle of twigs, the hlautteinar, used together as a single ritual set. Animals were slaughtered and their blood, hlaut, was collected in the bowl; the twigs were then dipped into the blood and used to sprinkle, or aspers, the temple altar, its interior walls, and the worshippers gathered for the feast, an act the sagas describe in terms suggesting it consecrated the space and the participants together rather than serving as a mere disposal of the sacrificial blood.

The twigs, rather than the bowl, were the tool actually applied to people and surfaces, functioning much as an aspergillum does in later liturgical traditions that likewise use a bundle or brush to distribute a consecrated liquid by sprinkling. Snorri's account specifically situates this practice at a formal midwinter blot hosted by the Norwegian king Hakon the Good, a nominally Christian ruler under strong pagan political pressure, and stages his reluctant participation as a set piece illustrating exactly how central the hlautteinar and hlautbolli were to a properly performed Norse sacrificial feast.

Because the hlautteinar and the hlautbolli appear together in both surviving saga accounts, functioning as a matched set rather than as independent objects, scholars of Norse religion, including Rudolf Simek in his standard dictionary of Northern mythology, generally treat them as two parts of one ritual instrument rather than as separately significant items: the bowl held the blood, the twigs applied it. That division of labour distinguishes the pairing from a general purpose sacred vessel, and it is the reason the two are classified here under different categories within the wider family of Norse sacred objects, the bowl as ceremonial equipment for holding a consecrated substance, the twigs as the instrument that actually performed the rite's central sprinkling action.

Both surviving descriptions come from Christian-era Icelandic writers working two to three centuries after the formal conversion of Iceland and Norway, which means neither Eyrbyggja Saga nor Heimskringla can be treated as a contemporary eyewitness ritual manual; scholars generally read them as preserving genuine folk memory of pre-Christian practice, filtered and shaped by a later literary and religious perspective, rather than as neutral ethnographic record. That caveat does not erase the underlying practice, blood sacrifice with formal aspersion using twigs and a bowl has close parallels in aspersion rites documented across other Indo-European and later Christian liturgical traditions, but it does mean specific procedural details beyond the core bowl-and-twigs pairing should be read with appropriate caution.
