Aþum Swerian: Swearers of Oaths?

Beowulf is a story about a doomed people who are destined for annihilation as a result of depredation, feuding, and cyclical inter-tribal violence. Yet, the violence described in the poem is not always outward but often occurs from within, as acts of intra-tribal violence frame much of the narrative. Even seemingly positive events are thus generally short-lived. Accordingly, in the eminence of King Hrothgar’s glorious construction of Heort, the narrator reveals the hall’s imminent doom:  

Sele hlifade  
heah ond horn-geap.   Heaðo-wylma bad
laðan liges.                Ne wæs hit lenge þa gen  
þæt se ecg-hete aþum swerian 
æfter wæl-niðe wæcnan scolde. (81-5)

The hall sheared upward, high and horn-vaulted. For the battle-surge it waited, loathsome fire. Nor was it long before the edge hate of aþum swerian must awaken for slaughter-spite.

Beowulf Manuscript, excerpt with aþum swerian.” BL, Cotton Vitellius a.vx. MS 130v, BL 133v.

This dire prediction identifies the causal agents of disaster as aþum-swerian. But given that this term is unattested and grammatically invalid, we are bound to ask: Who are these aþum-swerian? The conventional approach solves this conundrum by creating a new term in imitation of such copulatives as suhtergefaedaran (“nephew and uncle” from Beowulf), gisunfader (“son and father” from Heliand), and sunufatarungo (“son and father” from Hildebrandslied). Following these models, the editors of Klaeber 4 (120, 350, 437) emend the term to aþum-sweoran, thereby conjoining aþum (sons-in-law) and sweoran (fathers-in-law). Because this solution apparently predicts the sundering of vows between Ingeld and Hrothgar (2022-66), this emendation has become the dominant convention. 

Nevertheless, there are problems. First, the emended term, glossed as “sons-in-law and fathers-in-law,” differs markedly from the models, which are glossed as “nephew and uncle” and “son and father.” And though the term is indeed attested with the gloss “son-in-law,” the rendering aþum-sweoran is a hapax legomenon attested nowhere in the extant corpus of Old English literature. Making the invention yet more suspect is the well-attested phrase, sweor ond aþum (father-in-law and son-in-law), which would seem to preclude a need for the copulative. 

The proposed term also falls short in its narratological salience. There are no “sons-in-law” implicated in the violence that erupts at Ingeld’s wedding, only one “son-in-law.” Yet more problematic, this single crisis cannot account for the apocalyptic imagery that frames Heorot’s catastrophe. Prior to the prediction of calamity, the hall’s construction is marked by an array of tropes that suggest the Tower of Babel. As Tristan Major observes, “Hrothgar’s rise to power [64-79] and the building of his hall, Heorot, echoes Nimrod and the Tower of Babel” (242).” Likewise, as Daniel Anlezark observes, the hall’s destruction is marked by retributive images of Flood and Hellfire (336-7). In sum, the proposed solution leaves important problems unresolved. It inaccurately predicts “sons-in-law” in respect to Ingeld. And it does not account for the apocalyptic imagery of idolatry, flame, and fire that marks Heorot’s doom.

The Tower of Babel. London, British Library, Cotton Claudius B.IV, fol 19r. 

In this review, we promote an alternative initially proposed by Michael Alexander. This alternative interprets aþum as the plural dative “oaths” and emends swerian to the plural dative -swaran (swearers). The rendering “swearers of oaths,” acknowledged by Klaeber 4 as possible, has the advantage of relying on attested terms. The plural dative form aþum (oaths) occurs not only in the corpus but also in Beowulf, and the second term (-swara) occurs in a similar compound, man-swaran (criminal swearers). Yet more support for this construct can be found in the oath-swearing between Hengest and Finn. Here the term aðum also occurs as a plural dative, framing a parallel scenario in which oaths will be broken and a hall destroyed:

Fin Hengeste
elne, unflitme aðum benemde
þæt he þa wealafe weotena dome 
arum heolde, þæt ðær ænig mon 
wordum ne worcum wære ne bræce . . . .  (1097-100)

“Fin with Hengest without quarrel declared his oath that he would by his council’s judgment hold [the truce] with honor that any man there by word or deeds should not break the covenant . . . .”

The emendation to aþum-swaran also offers much stronger alignment with the narrative arc. Notably, this alignment begins with the paired disclosures that define Fitt I: Whereas the history of Grendel’s origin locates Cain’s act of murder as a calamity in the past, the prediction of murderous oath-swearers locates Heorot’s destruction as a calamity in the future. This parallel design is highly significant: In effect, it forges a link between Cain’s crime of kinship murder and the internecine violence that spells Heorot’s doom. This linkage, moreover, not only intimates the Danes’ ongoing state of iniquity but also explains the apocalyptic tropes that frame the hall’s calamity. Accordingly, Heorot’s doom emerges not as a circumstantial event caused by brawling Danes and Heathobards but as an in-kind retributive event that aligns perfidious Nordic warriors with the curse of exile from human joys, entailed in Cain’s crime and punishment.

Cain killing Abel with a scythe. Bible Historiale. British Library, MS Harley 4381, f.10r, 1403-1404.

Notably, also, the intimation of Danish perfidy is borne out across the narrative arc. Beowulf and the narrator declare Unferth’s fratricidal treachery; the narrator insinuates Hrothulf’s possible resentment against his uncle, Hrothgar; the lay of Finn and Hildeburh recounts the Danes’ violation of peace oaths in favor of murderous revenge; Hrothgar’s adoption of Beowulf sparks Wealhtheow’s resistance and her appeals to warriors in the hall; and Hrothgar violates his promise of protection to the Geats, potentially inciting Beowulf’s revenge. This surfeit of Danish treachery, in other words, aligns perfectly with the narrator’s revelation that “swearers of oaths” will soon incite violence.

For this reason, also, the reference to oath-swearers functions as a formula for suspense—a design that impels the audience to consider, in a fictive world replete with perfidy and oath-making, which of the oath-swearers will incite a conflagration? Will Unferth the fratricide murder again? Will Hrothulf avenge his displacement from the throne? Will one of the Danes retaliate against Hrothgar’s covenant with Beowulf, the foreigner? Will Wealhtheow incite the same kind of intertribal violence that erupts in the Frisians’ hall? Will Beowulf retaliate against Hrothgar for deserting his men?

The emendation to aþum-swaran presents a solution that is better attested and more meaningful than the conventional emendation to aþum-sweoran. As noted above, the gloss of “sons-in-law” does not possess predictive value regarding Ingeld, and the sundering of vows between Ingeld and Hrothgar cannot explain the apocalyptic imagery surrounding the disclosure of Heorot’s doom. Conversely, that same apocalyptic imagery aligns perfectly with a depiction of Danish society as inherently unstable, doomed to self-destruction, as the unchecked impulses of egoistic aggrandizement overcome the covenants that bind social order. Likewise, the depiction of Danish perfidy permeates the narrative arc. Accordingly, the disclosure of violent oath-swearers functions within an ingenious narrative design. It affords the schadenfreude of dramatic irony, as the audience anticipates a disaster the characters know not of. And it thus generates a game of blind corners, in which the audience’s knowledge of impending violence from oath-swearers charges subsequent events with anticipation and suspense.

Weigh Your Books! An Interview with Dr. Andrew Irving

This week, we’re revisiting the first published episode of “Meeting in the Middle Ages.” Back in 2022, we sat down with Dr. Andrew Irving, assistant professor of religion and heritage at the University of Groningen. We spoke to him about his journey to Medieval Studies, his work on the 11th century Uta Codex, why one should always weigh their books, and why liturgy is like a Wagnerian opera.

Dr. Irving’s story is one of a truly international scholar. A native of New Zealand who moved to the US to study for his PhD at Notre Dame, he now works in Europe on a broad range of medieval subjects. His stories of archival work highlight some of the unexpected challenges that researchers can face: limited access to resources, unconducive weather (it helps to examine books in “raking light”), or flat out denied permission to consult a manuscript. Traveling to another country to visit a library and examine its rarest materials can be intimidating, especially for young scholars. But Dr. Irving demonstrates that a personal connection and diligent preparation can pave the way for a smooth experience. It’s an instructive tale for young scholars, and sheds light on a part of scholarly work that may seem mysterious to the uninitiated.

Dr. Irving’s work is about place. His career has taken him all over the world, of course. But the place in which texts exist is also paramount. Through his work on texts like the Uta Codex, he provides some great examples of how a manuscript has to be considered in terms of its home. Where was it kept? What was the environment? What was the history of that home? Was it ever destroyed, raided, burned? If it was a written document, was it read aloud? To whom? Was it carried about? How much did it weigh? All of these questions must be asked to get at the truth of an object. A text has to be wrestled with on its own terms—in isolation—but this is only half the story. Each historical artifact is living history: it was created by someone for someone or something. We have to be prepared to engage with it in a multitude of ways. We must be historians, linguists, theologians, art historians, literary critics, and more. That is what it is to be a medievalist.

Thanks for listening. See you next time in the Middle Ages.

By the Bones of Saint Cuthbert: Books, Embroidery, and Bodily Incorruption

When the Vikings invaded the northeastern coast of Britain in 793, they raided the monastery at Lindisfarne. The monks fled – and they carried with them the remains of Saint Cuthbert.

His coffin not only contained a corpse but also material relics, the Saint Cuthbert Gospel among them. The book so well preserved in his coffin has been recognized as a marvel among medieval manuscripts, along with the Lindisfarne Gospels, which the monks also saved from destruction by the Danes. Much like these extraordinary books, the embroidery that survived alongside Saint Cuthbert’s body is remarkable for its rarity.

The Lindisfarne Gospels has, as the British Library says, “long been acclaimed as the most spectacular manuscript to survive from Anglo-Saxon England.” Created circa 700, the elaborately decorated manuscript contains the four Gospels, which recount the life of Christ, as well as other associated texts.

Cuthbert of Lindisfarne was born in 634 and spent his life as a monk, bishop, and hermit in the Kingdom of Northumbria. When he died in 687, he was buried at Lindisfarne. As the Venerable Bede recounts the story, Saint Cuthbert’s coffin was opened again 11 years later with the intention of removing his bones to a reliquary, but his body was found to be perfectly preserved.

From Bede’s “Life of Saint Cuthbert,” British Library MS 39943, dated 1180.

Under the duress of Danish attack, it was more than 100 years before the monks laid Saint Cuthbert to rest in Durham, where they settled in 995. Several artifacts accompanied Saint Cuthbert as he traveled posthumously around the English countryside, and the book and embroidery are very special for their survival.

The Saint Cuthbert Gospel was discovered when the coffin was opened at Durham Cathedral in 1104, and like the body of its patron, the book remained incredibly well preserved. Dated to the early 8th century, it is the earliest European book to retain an original, intact binding.[1] The covers are made from goatskin that has been dyed red and decorated; the tooled leather is stretched over wooden boards, most likely birch. It is a pocket-sized book measuring 5.4 by 3.6 inches, and the manuscript contains the Gospel of Saint John.

Housed at the British Library in London, the Saint Cuthbert Gospel can sometimes be seen on display in the Treasures of the British Library exhibition, sometimes alongside the Lindisfarne Gospels. Photo of the front cover of the Saint Cuthbert Gospel, courtesy of the British Library.

The British Library’s description of the binding beautifully correlates the book’s cover with its content. On its front cover, “the central motif of a stylised vine sprouting from a chalice reflects Christian imagery from the eastern Mediterranean. The plant on the cover of the Gospel has a central leaf or bud and four fruits, echoing the text, ‘I am the vine, you are the branches’, from St. John’s Gospel 15:5.”[2] On the back cover appears “rectangular borders containing a geometric, step-pattern double-armed cross, recalling John’s central role in the Crucifixion narrative.”[3]

The other relics were discovered much later when Saint Cuthbert’s tomb was opened in 1827. In addition to the saint’s body, Canon James Raine found a pectoral cross, a portable altar, an ivory comb, and a set of embroidered vestments.[4] The vestments, or religious robes, date between 909 and 916 and are the earliest pieces of embroidery that survive from the medieval period in England.

Only a few pieces of Anglo-Saxon embroidery survive at all, and these pieces are unique among the extant examples in that they feature full-length human figures. The vestments include a stole decorated with figures of Old Testament prophets and Apostles, as well as a maniple, a girdle, and bracelets. They are made from Byzantine silk with silk and gold thread decoration. According to inscriptions on the fabric, the vestments were commissioned by Queen Aelfflaed for the Bishop of Winchester and produced between 909 and 916. Her stepson, King Athelstan, who ruled England from 927 to 939, placed them in Saint Cuthbert’s tomb when he visited the shrine in 934.

The style of embroidery called Opus Anglicanum, or English Work, was used on clothing, hangings, and other textiles, often created with silk and gold or silver-gilt threads stitched on linen or velvet backgrounds. Between the late 12th and mid-14th centuries, these luxury goods were in great demand across Europe. Often they were procured as diplomatic gifts, and they were very expensive. They were produced for both secular and ecclesiastical use, but most of the surviving examples were designed for liturgical use like those found alongside Saint Cuthbert.

Although English embroidery was renowned for its beauty during the medieval period, the majority has been lost to neglect or destroyed for the extraction of precious metals or stones, such as pearls and other jewels mentioned in inventory descriptions. Fragments, however, can be found in museums, and one of the most substantial collections of Opus Anglicanum can be found at the Victoria and Albert Museum in London.

Embroidered in the Opus Anglicanum style, the Butler-Bowdon Cope is a ceremonial cloak that was created circa 1330-50 for use in church services and processions. The embroidery incorporates gold, silver, and colored silks, as well as freshwater seed pearls and glass beads, and depicts events from the life of the Virgin Mary.

The vestments recovered from Saint Cuthbert’s tomb can be seen on display at Durham Cathedral, where visitors can view the entire Treasures of Saint Cuthbert collection. The oak coffin made to cradle the saint’s body when he was found incorrupt in 698 also resides among the relics, its own fragmented body a reminder of what arduous travels medieval artifacts endure to remain with us in our own time.
