Grendelโs mother has long been regarded by scholars as the least monstrous of the threeโnot being an obvious vampire-cannibal like Grendel nor a fire-breathing dragon. Her vengeful response to the death of her son, and her decision to continue the feud between the Grendelkin has been regarded as ethical (within the broader context of warrior ethos), legal (within the context of early medieval Norse and English laws), and even heroic (aligned with the heroism as depicted in the poem).

While I would generally agree with this broad characterization of Grendelโs mother, and there is no doubt that her actions mirror those of any avenging warrior in Beowulf, to erase her monstrosity seems to ignore at least some of the evidence. While I do not find her maternity at all indicative of abject horror (indeed quite the opposite as it is her identity as โmotherโ that humanizes her in my view), certain terms used to describe her and indeed everything from her association as Caines cynn โCainโs kinโ (107; 1261-65) and the hellish descriptions of her lair suggest some measure of monstrosity embedded in her character. And for this Halloween, we will spend some time unpacking the nature of her monstrosity.
I would contend that the main reason scholars argue about Grendelโs motherโs monstrosity and characterization is because of her enigmatic design. As I point out in my dissertation, riddles encode Beowulf, and, in my opinion, employ riddling rhetorical strategies, especially imitation, equivocation, esotericism and paradox. These obfuscations help account for the many irregularities observed in the poem the scholars have scratched their heads over for more than a century and help explain why often the heroes looks like the monstersโand the monsters like the heroes.

Because of the influence of riddling rhetorical strategies on Beowulf, turning to the Anglo-Latin enigmata tradition is an especially fruitful practice, especially in explorations of monstrosity in the poem. Indeed, monsterized riddles have long been a feature starting with the late classical enigmatist, Symphosius, who establishes the Anglo-Latin tradition, includes numerous riddles on wondrous creatures, such as the phoenix (Enigma 31). Similarly, Aldhelmโs enigmata also feature numerous monsterized riddles, in some cases the solution is a wondrous creature (as with Symphosiusโ paradoxical phoenix-riddle), in other cases the mundane is made monstrous through imitation, and the monsterization is another mechanism of obfuscation (as in Aldhelmโs Enigma 97 solved nox). Even Boniface, whose riddles center on vices and virtues, monsterizes his vice-riddles in the mode of Prudentiusโ Psychomachia, a popular classroom text in early medieval English which depicts vices as monsters in an allegorical epic.

But what does this have to do with Grendelโs monstrous mother? Letโs start with her introduction and the complex portrait it paints:
รรฆt gesyne wearรพ,
widcuรพ werum, รพรฆtte wrecend รพa gyt
lifde รฆfter laรพum, lange รพrage,
รฆfter guรฐceare: Grendles modor.
Ides aglรฆcwif yrmรพe gemunde,
se รพe wรฆteregesan wunian scolde,
cealde streamas, siรพรฐan Cain wearรฐ
to ecgbanan angan breรพer,
fรฆderenmรฆge. He รพa fag gewat,
morรพre gemearcod, mandream fleon,
westen warode.
โThat became manifest, widely known to men, that an avenger still lived after the hostile one, for a long time, after war-grief: Grendelโs mother. A lady, a fearsome woman remembered misery, he who must inhabit the terrible-waters, the cold streams because Cain became the edge-slayer to his only brother, kin of the same father. He then went hostile, marked by murder, fled the joys of men, inhabiting the wilderness.โ
Beowulf, 1255-65.
The first term used to describe Grendelโs mother emphasizes her desire for vengeance. The narrator names her a wrecend โavengerโ (1256) โan appropriate title considering her entire characterization is framed by revenge and feudingโand her motive is thrice repeated almost verbatim and with language that could apply equally to avenging heroes in the poem (1276-78, 1339-1340, 1546). Moreover, Grendelโs motherโs is thrice described as wif โwomanโ (1259, 1519, 2120,) and even twice as an ides โladyโ (1259, 1351) establishing gender as one of the pillars of her characterization, alongside her roles as avenger and mother. Kinship ties are further emphasized when Grendelโs mother is described as Grendles maga โGrendelโs female relativeโ (1391) and twice as Grendles mรฆg โGrendelโs kinsmanโ (2006, 2353), which account for her desire for revenge in upholding the warrior ethics and continuing the feud between the Danes and the Grendelkin.

Moreover, like the monstrous vices in Prudentiusโ Psychomachia and Bonifaceโs Enigmata, the avengerโGrendelโs motherโis clearly wondrous and monstrous in certain descriptions of her. She and her lake monsters are wรฆteregesa โwater-terrorsโ (1260). Grendelโs mother is called se broga โthe terrorโ (1260), and together with her son, she is described as mihitig manscaรฐa โman-slayerโ (1339), micle mearcstapa โgreat marked-wandererโ (1348), dyrna gast โsecret spiritโ (1357), รฆlwiht โalien thingโ (1518), thrice as ellorgรฆst โforeign spiritโ (1349, 1617, 1621) and even deofol โdevilโ (1680). She is even described as a merewif mihtig โmighty mermaidโ (1519), aglรฆcwif โfearsome warrior womanโ (1259) or wif unhyre โuntamed womanโ (2120), grundwyrgenne โground wolfโ (1518) and twice is characterized with the compound a brimwulf โsea-wolfโ (1506, 1599).
It is my contention that descriptions of Scyllaโa classical monster, famously featured in the Odyssey and popular in Anglo-Latin literature contemporary with Beowulfโlikely influence the characterization of Grendelโs mother, a riddle embedded in the poetic compounds used to describe her and in the depiction of her monstrous lair.

Scylla is a monstrous sea creature from Greek mythology, known for inhabiting a narrow strait opposite the whirlpool Charybdis. She often has multiple heads with each head bearing a set of sharp, ravenous teeth. Scylla’s body is a womanโs often combining serpentine, aquatic and canine features. She emerges from a rocky cliffside and narrow passage where she lives. She preys on passing sailors, snatching them from ships with her many heads and her โsea dogsโ which accompany her. Once a beautiful nymph, she becomes cursed and exiled.
Scylla is the riddle-subject of Aldhelmโs Enigma 95 (solved Scilla) and is featured in his prose De uirginitate (X). Aldhelmโs Enigma 95 describes Scylla as follows:
Ecce, molosorum nomen mihi fata dederunt
(Argolicae gentis sic promit lingua loquelis),
Ex quo me dirae fallebant carmina Circae,
Quae fontis liquidi maculabat flumina uerbis;
Femora cum cruribus, suras cum poplite bino
Abstulit immiscens crudelis uerba uirago.
Pignora nunc pauidi refereunt ululantia nautae,
Tonsis dum trudunt classes et caerula findunt.
Uastos uerrentes fluctus grassante procella,
Palmula qua remis succurrit panda per undas,
Auscultare procul quae latrant inguina circum.
Sic me pellexit dudum Titania proles,
Ut merito vivam salsis in fluctibus exul.
โLook, the Fates gave me the name of dogsโthus does the language of the Greeks render it in wordsโever since the incantations of dread Circe, who stained the waters of the flowing mountains with her words, deceived me. Weaving words, the cruel witch deprived me of thighs together with shins, and calves, together with knees. Terrified mariners relate that, as they impel their ships with oars and cleave the sea, sweeping along the mighty wave while the tempest rages, where the broad blade of howling offspring that bark about my loins. Thus the daughter Titan [scil. Circe] once tricked me, so that I should live as an exileโdeservedlyโin the salty waves.โ
Lapidge and Rossier, Aldhelm: The Poetic Works, 91.
In this riddle, solved Scylla (Scilla), Aldhelm emphasizes her canine connection, and gives a reference to her origin in Greek mythology and her transformation at the hands of the witch, Circe. There is also mention of the danger she poses to any who sail by her watery abode, alongside her โhowling offspring that barkโ about her an further threaten wayward travelers.

Scylla also appears twice in the Liber monstrorum (I.14, II.19), where she is described in detail. This first mention from Liber monstrorum I.14 in the section on humaniod monsters is as follows:
Scylla monstrum nautis inimicissimum in eo freto quod Italiam et Siciliam interluit fuisse perhibetur capite quidem et pectore uirginali sicut sirenae, sed luporum uterum et caudas delfinorum habuit. Et hoc sirenarum et Scyllae distinguit naturam quod ipsae morifero carmine mauigantes decipiunt et illa per uim fortitudinis marinis succinta canibus miserorum fertur lacerasse naufragia.
โIt is reckoned that Scylla has been the monster most hostile to sailors in that channel which washes between Italy and Sicily, having indeed the head and chest of a maiden (like the sirens), but the belly of a wolf and the tail of dolphins. And what distinguishes the nature of the sirens from Scylla is that they deceive seamen by their deadly song, whilst she with the strength of her force, girt about with sea-dogs, is said to have mangled the wrecks of the unfortunate .โ
Orchard, Pride and Prodigies, 266-67.
This description emphasizes her superlative hostility [inimicissimum]โsimilar to Grendelโs motherโs characterization as an aglรฆcwif โfearsome warrior womanโ (1259) or wif unhyre โuntamed womanโ (2120). Emphasis on the narrow channel where Scylla resides shifts to her hybrid representation with โthe head and chest of a maiden (like sirens) but the belly of a wolf and the tail of a dolphinsโ (fuisse perhibetur capite quidem et pectore uirginali sicut sirenae, sed luporum uterum et caudas delfinorum habuit). This establishes Scylla as a woman-canine-marine creature, combining โmaidenโ (virgo), โwolfโ (lupus), and โdolphinโ (delphinus) parts. Moreover, she is twice compared to the treacherous sirens, while explaining that unlike the sirens, who use song to ensnare their victims, Scylla uses force, violence and her mighty strength, with her โsea-dogsโ (marinis canibus) to take down unfortunate sailors who enter her domain.

In the second section, centered on bestial monsters, there is an entry on the sea-beasts of Scylla. Liber monstrorum II.19 reads as follows:
fingunt quoque poetae inmari Tyrrheno ceruleos esse canes, qui posteriorem corporis partem cum piscibus habent commune. Ipsis quoque Scyllam ratem Ulixis lacerans marinis succincta canibus describitur.
โthe poets also image that there are azure dogs in the Mediterranean, the hind parts of whose bodies they share with fish; also girt round with these same sea-dogs Scylla is described tearing apart the ship of Ulyssesโ
Orchard, Pride and Prodigies, 266-67.
This entry focuses on the โazure dogโ (ceruleos canes) or โsea dogsโ (marinis canibus) of Scylla, which are described as featuring canine heads and legs, but โthe hind parts of whose bodies they share with fishโ (qui posteriorem corporis partem cum piscibus habent commune) making them a canine-marine hybrid creature. Scylla is directly mentioned in connection with her accompanying sea-monsters, and the passage directly references the struggles of Odysseus [i.e. Ulysses] when he encounters Scylla on his epic journey home.

The key features of Scyllaโs narrow channel are present also in the monster-mere found in Beowulf which is the home and hall of the Grendelkin. Grendelโs Motherโs lair is described in the poem as follows:
Hie dygel lond
warigeaรฐ, wulfhleoรพu, windige nรฆssas,
frecne fengelad, รฐรฆr fyrgenstream
under nรฆssa genipu niรพer gewiteรฐ,
flod under foldan.
โThey [Grendelkin] inhabit the secret land, the wolf-slopes, the windy narrows, the dangerous fen-path, where the mountain stream cascades downward under the cover of cliffs, the flood under the land.โ
Beowulf, 1357-61.
This description emphasizes the dangerous narrows and the crafty cliffs surrounding the monstrous abode and in this way echoes Scyllaโs watery domain. In this passage are numerous references to the steep and narrow geography, especially in descriptions of the wulfhleoรพu windige nรฆssas โwolf-slopes (and) windy narrowsโ (1358), and fyrgenstream under nรฆssa genipu, โa mountain river under the cover of cliffsโ (1359-60). As Beowulf enters the waves, he finds himself, like those caught by Scylla in the Odyssey, in a violent struggle for his life at the hands of a ferocious woman who pulls him to the depths of her haunted lake. The narrator explains how:
Bรฆr รพa seo brimwylf, รพa heo to botme com,
hringa รพengel to hofe sinum,
swa he ne mihte, no he รพรฆs modig wรฆs,
wรฆpna gewealdan, ac hine wundra รพรฆs fela
swencte on sunde, sรฆdeor monig
hildetuxum heresyrcan brรฆc,
ehton aglรฆcan. รฐa se eorl ongeat
รพรฆt he in niรฐsele nathwylcum wรฆs,
รพรฆr him nรฆnig wรฆter wihte ne sceรพede,
ne him for hrofsele hrinan ne mehte
fรฆrgripe flodes; fyrleoht geseah,
blacne leoman, beorhte scinan.
Ongeat รพa se goda grundwyrgenne,
merewif mihtig .
โWhen she came to the bottom, the sea-wolf bore the prince of rings to her hall, so he could not, no matter how brave he was, wield weapons, but so many wonders afflicted him while swimming, many a sea-beast poked the battle-armor with battle-tusks, harassed the fearsome assailant (Beowulf). Then the man perceived that he was in some kind of hostile-hall, where no water could harm them at all, nor could the sudden grasps of the flood touch them because of the roofed-hall. He saw firelight, pale illumination brightly shining. Then the good one (Beowulf) perceived the bottom-wolf, the mighty sea-woman.”
Beowulf, 1506-1519.

In reading this passage from the poem, we can observe numerous parallels between Grendelโs mother and Scylla, which I believe suggests that the classical monster, frequently featured in Anglo-Latin texts, may have influenced the depiction and characterization of Grendlโs mother. Just like with Scyllaโs channel, the monster-mere in Beowulf includes sea-creatures that attack anyone who enters their watery lair. Both Scylla and Grendelโs mother are ancient, cursed and exiled monsters, the former as a result of a witchโs curse, the latter is prediluvian, cursed and marked as kin of Cain. Grendelโs mother seems to travel with sea-beasts (nicoras) which resemble Scylla’s sea-dogs. Both Scylla and Grendelโs mother are hybrid women monstersโfeaturing both canine or lupine characteristics (as indicated by her description as brimwulf “sea-wolf” and grundwyrgenne “bottom-wolf”) characteristics and piscine or serpentine characteristics (as indicated by her description as merewif “mermaid”). And, both Scylla and Grendelโs mom occupy a craggy narrow passage that is terrifying and dangerous for sailors or sea-men.
While I would not push so far as to contend that Grendelโs mother is intended as a literal representation of Scylla, and while I agree with others who have observed her ethically complex characterization, it seems plausibleโeven probableโthat the famous Scylla could have influenced her enigmatic monsterization. At the very least, many counted among the learned audiences of Beowulf in early medieval England would likely have discerned the numerous and noteworthy parallels between these two monstrous women.
