Jorund

Notes:

Jorund or Jörundr (5th century) was a Swedish king of the House of Yngling. He was the son of Yngvi, and he had reclaimed the throne of Sweden for his dynasty from Haki (the brother of Hagbard, the hero of the legend of Hagbard and Signy, and Snorri cites two kennings from this legend Sigar's steed and Hagard's fell noose, when telling of Jorund).

Snorri Sturluson relates that when Jorund was young he used to travel the seas and plunder with his brother Erik, and they were great warriors. One summer they plundered in Denmark where they met another pillager, King Gudlög of Hålogaland (a province in Norway) with whom they fought. They took him prisoner and carried him ashore at Stromones where they hanged him. Gudlaug's surviving companions raised a mound over him there.

Snorri then cites the poem Háleygjatal by a Norwegian skald named Eyvindr skáldaspillir:

En Guðlaugr
grimman tamdi
við ofrkapp
austrkonunga
Sigars jó,
er synir Yngva
menglötuð
við meið reiddu.
Og náreiðr
á nesi drúpir
vingameiðr,
þar er víkur deilir,
þar er fjölkunnt
um fylkis hreyr
steini merkt,
Straumeyjarnes.
By the fierce East-kings' cruel pride,
Gudlog must on the wild horse ride --
The wildest horse you e'er did see:
'Tis Sigur's steed – the gallows tree.
At Stromones the tree did grow,
Where Gudlog's corpse waves on the bough.
A high stone stands on Stromo's heath,
To tell the gallant hero's death.
This act rendered the Swedish princes, Eric and Jorund, even more famous and they were thought of as even greater men. When they learnt that King Haki no longer had his forces around him, they decided to take care of their enemy. They assembled a large force that was joined by Swedes as they approached. They entered Mälaren (a bay at the time) and steered towards Uppsala. They left their ships at the Fyris Wolds and were met by Haki who had fewer men. Haki was a brutal fighter and managed to turn the tide of the battle. He slew Erik who held the banner and Jorund retreated with his men. Haki had been seriously wounded and died.

Jorund then ruled Sweden at Uppsala, but he usually spent the summers pillaging. One summer, he plundered in Jutland and entered Limfjorden, where he continued the pillaging. They anchored in Oddesund (before a storm in 1825, it was near the innermost part of the fjord and almost 200 km from its mouth) but were discovered by the Norwegian pirate Gylaug of Hålogaland, the son of Gudlaug. Gylaug and his men attacked them and were joined by local forces who wanted revenge. As Jorund was vastly outnumbered (and had to run an almost 200 km long gauntlet to get out of the fjord), he lost the battle, and Gylaug had him hanged.

Snorri illustrates this event with the stanza from Ynglingatal:

Varð Jörundr
hinn er endr of dó,
lífs of lattr
í Limafirði,
þá er hábrjóstr
hörva Sleipnir
bana Goðlaugs
of bera skyldi;
ok Hagbarðs
hersa valdi
höðnu leif
at halsi gekk.
Jorund has travelled far and wide,
But the same horse he must bestride
On which he made brave Gudlog ride.
He too must for a necklace wear
Hagbert's fell noose in middle air.
The army leader thus must ride
On Horva's horse, at Lymfjord's side.
The Historia Norwegiæ presents a Latin summary of Ynglingatal, older than Snorri's quotation, continuing after Yngvi (called Ingialdr):

Post hunc filius ejus Jorundr, qui cum Danos debellasset, ab eisdem suspensus in loco Oddasund in sinu quodam Daciæ, quem Limafiorth indiginæ appellant, male vitam finivit. Iste genuit Auchun (i.e. Aun) [...]

After him his son Jorund ruled, who ended his days unhappily once he had fought a war against the Danes, who hanged him at Oddesund, on an arm of the sea in Denmark which the natives call Limfjorden. He became the father of Aukun, [...]

The even earlier source Íslendingabók also cites the line of descent in Ynglingatal and it gives the same line of succession: xiiii Yngvi. xv Jörundr. xvi Aun inn gamli.

The Skjöldunga saga and the Bjarkarímur tell that Jorund was defeated by the Danish king Fróði (corresponds to the Heaðobard Froda in Beowulf), who made him a tributary and took his daughter. The daughter gave birth to Halfdan, but another woman became Fróði's legitimate wife and gave him an heir named Ingjaldr (corresponds to the Heaðobard Ingeld in Beowulf). Together with one of his earls, Swerting, Jorund conspired against Fróði and killed him during the blót.

Notes:

Yngvi and Alf were two legendary Swedish kings of the House of Yngling. Some versions indicate they were brothers or other close relations. They killed each other.

According to Ynglingatal, Historia Norwegiae and Ynglinga saga, Yngvi and Alf were the sons of Alrik.

Snorri Sturluson relates that Yngvi was an accomplished king: a great warrior who always won his battles, the master of all exercises, generous, happy and sociable. He was both loved and famous.

Alf was unsociable and harsh and stayed at home instead of pillaging in other countries. His mother was Dageid, the daughter of king Dag the Great from whom is descended the Dagling family. Alf was married to Bera who was happy and alert and a very lovable woman.

One day in the autumn, Yngvi returned to Uppsala from a very successful Viking expedition which had rendered him famous. He used to spend time at the drinking table until late in the night, like Bera, and they found it pleasant to talk to each other. Alf, however, preferred to go to bed early and he started to tell her to go to bed early as well so that she did not wake him. Then Bera used to answer that Yngvi was much better for a woman than Alf, an answer that was getting on Alf's nerves.

One evening, the jealous Alf entered the hall and saw Yngvi and Bera converse on the high seat. Yngvi had a short sword in his lap and the other guests were too drunk to see that Alf had arrived. From under his cloak Alf drew a sword and pierced Yngvi. Yngvi, mortally wounded, got up, drew his own short sword and slew Alf. They were buried in two mounds on the Fyrisvellir (Fyris Wolds).

Alf was succeeded by his son Hugleik.

The poem in Ynglingatal:

Ok varð hinn,
er Alfr of vá
vörðr véstalls,
of veginn liggja,
er dölingr
dreyrgan mæki
öfundgjarn
á Yngva rauð.
Var-a þat bært
at Bera skyldi
valsœfendr
vígs of hvetja,
þá er brœðr tveir
at bönum urðusk,
óþurfendr,
of afbrýði.[1][2]
I tell you of a horrid thing,
A deed of dreadful note I sing --
How by false Bera, wicked queen,
The murderous brother-hands were seen
Each raised against a brother's life;
How wretched Alf with bloody knife
Gored Yngve's heart, and Yngve's blade
Alf on the bloody threshold laid.
Can men resist Fate's iron laws?
They slew each other without cause.[3][4]
The Historia Norwegiæ presents a Latin summary of Ynglingatal, older than Snorri's quotation:

Cujus [Hogne, i.e. Agne ] filius Ingialdr in Swethia a fratre suo ob infamiam uxoris ejus occisus est, quæ Bera dicta est (hoc nomen latine sonat ursa). Post hunc filius ejus Jorundr [...][5]

His [Agne's] son, Ingjald, was murdered in Sweden by his own brother because he had brought discredit on the latter's wife, whose name was Bera (Ursa in Latin). After him his son Jorund ruled, [...][6]

Ingjaldr is held to be an error for Yngvi.[7] Unlike Ynglingatal, Historia Norwegiæ gives Agne as Yngvi's predecessor. Instead Alrekr precedes Agne and Agne is succeeded by Yngvi. The even earlier source Íslendingabók cites the line of descent in Ynglingatal and it gives the same line of succession as Historia Norwegiæ: xi Dagr. xii Alrekr. xiii Agni. xiiii Yngvi. xv Jörundr.[8]

Ari Frodi's Younger Íslendingabók
According to Ari Frodi's line of Swedish kings Yngvi was the son of Agne, and not of Agne's son Alrik.

Gesta Danorum
In Gesta Danorum, Alf (Alverus) was the father of Yngve (Ing) and Ingjald (Ingild). Ingjald, in his turn was the father of Sigurd Hring and the grandfather of Ragnar Lodbrok.

Notes:

Alaric and Eric (Old Norse Alrekr and Eiríkr ), were two legendary kings of Sweden.

In the Ynglinga saga
According to the Ynglinga saga, Alaric and Eric were sons and heirs of the previous king Agni by his wife Skjálf. They shared the kingship. They were mighty both in war and sport, but were especially skillful horsemen and vied with one another about their horsemanship and their horses.

One day they rode off from their retinue and did not return. They were found dead with their heads battered but no weapons with them save the bridle bits of their horses. Accordingly it was believed that they had quarreled and come to blows and had slain each other with their bridle bits. They were succeeded by Alaric's sons Yngvi and Alf.

However, in other sources, only Alaric died, and in the piece of Ynglingatal quoted by Snorri Sturluson it is only Alaric who dies explicitly. Eric's death seems to be a misunderstanding on Snorri's part due to an influence from the succeeding kings (see also the other sources below):

Fell Alrekr,
þar er Eiríki
bróður vápn
at bana urðu,
ok hnakkmars
með höfuðfetlum
Dags fríendr
of drepask kváðu;
frá-at maðr áðr
eykja greiði
Freys afspring
í folk hafa.[1][2]
Alrek fell, by Eric slain,
Eric's life-blood dyed the plain,
Brother fell by brother's hand;
And they tell it in the land,
That they worked the wicked deed
With the sharp bits that guide the steed.
Shall it be said of Frey's brave sons,
The kingly race, the noble ones,
That they have fought in deadly battle
With the head-gear of their cattle?[3][4]
Ynglingatal then gives Yngvi and Alf as Alrek's and Eirík's successors.

The Historia Norwegiæ presents a Latin summary of Ynglingatal, older than Snorri's quotation:

Qui [Dagr] genuit Alrik; hunc frater suus Erikr freno percussit ad mortem. Alricr autem genuit Hogna [...][5]
This man [Dag] engendered Alrek, who was beaten to death with a bridle by his brother, Eirik. Alrek was father to Agne, [...][6]

Hogna is an error for Agne.[5] Unlike Ynglingatal, Historia Norwegiæ gives Dagr as Alrekr's predecessor. Instead Alrekr precedes Agne and Agne is succeeded by Yngvi (incorrectly called Ingialdr[5]). The even earlier source Íslendingabók cites the line of descent in Ynglingatal and it gives the same line of succession as Historia Norwegiæ: xi Dagr. xii Alrekr. xiii Agni. xiiii Yngvi.[7]

In Gautreks saga and Hrólfs saga Gautrekssonar
Gautreks saga also makes Alrek and Eirík sons of Agni by Skjálf and co-kings and it was to them that the warrior Starkad fled after his slaying of King Vikar. Starkad served them first as a companions on their viking expeditions and then, after Alrek and Eirík had settled down, went on further Viking expeditions alone.

But King Alrek had a short life, for Eirík struck Alrek dead with a bridle when they were out to train their horses and then ruled as sole ruler over Sweden. This version says that Eirík reigned for a long time as told in Hrólfs saga Gautrekssonar (Saga of Hrólf son of Gautrek).

This second saga introduces Thornbjörg, the daughter of King Eirík and Queen Ingigerd, who was a skillful shieldmaiden and ruled over part of the kingdom. Thornbjörg even called herself King Thorberg. But eventually she fell in love with Hrólf son of Gautrek and agreed to marry him, at which point she gave up her weapons to her father King Eirík and took up embroidery.

In Gesta Danorum
Saxo Grammaticus in Book 5 of his Gesta Danorum introduces Ericus Desertus, that is Erik the Eloquent, son of a champion named Regnerus (Ragnar), both Norwegians in the service of King Gøtarus (Götar) of Norway, a monarch otherwise unknown. This Erik is likely to be the Eirík the Eloquent or Eiríkr the Wise in Speech mentioned by Snorri Sturluson in the Skáldskaparmál as being of Ylfing lineage. But he otherwise has left no clear record in surviving Norse literature.

Saxo makes up for it by telling at greath length of Erik's amusing deeds. He relates how Erik outwitted all foes with clever tricks and became the counselor of Fróði son of Fridleif, king of Denmark. Erik's expeditions on Fróði's behalf always went well because of Erik's cunning and way with words. Erik finally married Fróði's sister Gunvara and Erik's elder half-brother Rollerus (Roller) was made king of Norway.

Saxo then brings in a king of the Swedes named Alricus (Alrik) who corresponds to Alrek of the Norse tradition. Alrik was at war with Gestiblindus king of the Gautar (Geats) and Gestiblindus now sought Fróði's aid. (In the Norse Hervarar saga Gestumblindi is the name assumed by the disguised Odin and it is possible that this Gestiblindus is also Odin in disguise.)

Erik and Skalk the Scanian pursued the war and slew Alrik's son Gunthiovus (Old Norse Gunnþjófr) leader of the men of Vermland and Solongs. Then occurred a parley and secret interview between Alrik and Erik in which Alrik attempted to win Erik over to his cause. When this failed, Alrik asked that the war be settled by a single combat between himself and Gestiblindus. Erik refused the offer because of Gestiblind's unfitness and advanced years but made a counter-offer to fight such a duel with Alrik himself if Alrik were willing. The fight occurred straightaway. Alrik was slain and Erik seemed to be fatally wounded so that a report actually came to King Fróði that Erik was dead. Indeed Erik was long in recovering. However Fróði was disabused when Erik himself returned announcing that Fróði was now also king of Sweden, Värmland, Helsingland, and Soleyar. Fróði then gave all those lands to Erik to rule directly and also gave Erik the two Laplands, Finland, and Estonia as dependencies paying annual tribute.

Saxo explains that this Erik was the first Swedish king to be called Erik but that after him it became a very common name among the Swedish kings. He also writes that Erik met and helped the champion Arngrim, an account that agrees with Hervarar saga, where Arngrim's sons meet Erik's successor Yngvi (see e.g. Angantyr and Hjalmar).

That the duel occurred at the end of a "secret interview" suggests that Alrik and Erik were alone when they fought just as were their counterparts in the Norse accounts. That Erik was believed to have died suggests knowledge of the Ynglinga saga version in which both fighters met their death. There is no mention of horse bridles. But Erik is not elsewhere a great duelist or champion but instead a trickster who wins through stratagems and deceiving words so that is it likely that Saxo or his source passed over a stratagem in which a horse bridle played a part.

Saxo also mentions Starkad's stay in Sweden in Book 6 in a summary of Starkad's life up to that point in his history. But Saxo does not indicate what king or kings then ruled Sweden, saying only:

... he went into the land of the Swedes, where he lived at leisure for seven years' space with the sons of Frø.

Frø is of course the god Frey, the ancestor of the Swedish dynasty.

At the beginning of Book 6, Saxo notes that Erik died of a disease and was succeeded by his son Haldanus (Halfdan). Halfdan was later slain by rivals for the throne but the warrior Starkad established Halfdans' heir Siward as the new king. Siward's daughter Signe was married to King Harald of Denmark who was co-king his brother Fróði. Later Harald's son Halfdan, now king of Denmark, slew Siward in war. But Siward's grandson Erik, the son of Halfdan's uncle Fróði by Signe, the direct heir to the throne, now rose up against Halfdan. After a long war this second Erik was captured by Haldfan and left in the woods in chains to be devoured by beasts. With him, it seems, the Swedish line of Erik the Eloquent, as set forth by Saxo, came to an end.

Commentary
It is not clear whether or not the accounts in the Gesta Danorum and the accounts in the Ynglinga saga' tales of a Danish king named Halfdan who became king of Sweden are at all related. See Halfdan.

Traditions of twin brothers connected with horses appear are a commonplace in Indo-European cultures as are foundation legends about two twin brothers, one of whom kills the other. It is possible that Alrek and Eirik are reflexes of such traditions.

Saxo's identification of the legendary Eirík the Eloquent with the legendary Swedish king Eirík probably originated as a flourish by a pro-Danish or pro-Norwegian story teller.

Notes:

Agne, (English: Agni), Hogne or Agni Skjálfarbondi was a mythological king of Sweden, of the House of Yngling.


Agne being hanged by his wife Skjalf. Artwork by Hugo Hamilton, 1830

King Agni's Barrow just southeast of Sollentuna Station in Sweden.
Snorri Sturluson relates that he was the son of Dag the Wise, and he was mighty and famous. He was also skilled in many ways.

One summer, he went to Finland with his army where he pillaged. The Finns gathered a vast host under a chief named Frosti.[1]

A great battle ensued which Agne won and many Finns were killed together with Frosti. Agne then subdued all of Finland with his army, and captured not only great booty but also Frosti's daughter Skjalf and her kinsman Logi.[2]

Agne returned to Sweden and they arrived at Stocksund (Stockholm) where they put up their tent on the side of the river where it is flat. Agne had a torc which had belonged to Agne's great-great-great-grandfather Visbur. Agne married Skjalf who became pregnant with two sons, Erik and Alrik.

Skjalf asked Agne to honour her dead father Frosti with a great feast, which he granted. He invited a great many guests, who gladly arrived to the now even more famous Swedish king. They had a drinking competition in which Agne became very drunk. Skjalf saw her opportunity and asked Agne to take care of Visbur's torc which was around his neck. Agne bound it fast around his neck before he went to sleep.

The king's tent was next to the woods and was under the branches of a tall tree for shade. When Agne was fast asleep, Skjalf took a rope which she attached to the torc. Then she had her men remove the tent, and she threw the rope over a bough. Then she told her men to pull the rope and they hanged Agne avenging Skjalf's father. Skjalf and her men ran to the ships and escaped to Finland, leaving her sons behind.

Agne was buried at the place, now called Agnafit, which is east of the Tauren (the Old Norse name for Södertörn) and west of Stocksund.

Þat tel ek undr,
ef Agna her
Skalfar ráð
at sköpum þóttu,
þar gœðing
með gullmeni
Loga dís
at lopti hóf
svalan hest
Signýjar vers.[3][4]
How do ye like the high-souled maid,
Who, with the grim Fate-goddess' aid,
Avenged her sire? – made Swithiod's king
Through air in golden halter swing?
How do ye like her, Agne's men?
Think ye that any chief again
Will court the fate your chief befell,
To ride on wooden horse to hell?.[5][6]
Ynglingatal then gives Alrekr and Eiríkr as Agne's successors.

The Historia Norwegiæ presents a Latin summary of Ynglingatal, older than Snorri's quotation:

Qui [Dagr] genuit Alrik; hunc frater suus Erikr freno percussit ad mortem. Alricr autem genuit Hogna; istum uxor sua juxta locum Agnafit, qui nunc Stokholmr dicitur, propriis manibus interfecit suspendendo ad arborem cum catena aurea. Cujus filius Ingialdr [...][7]

This man [Dag] engendered Alrek, who was beaten to death with a bridle by his brother, Eirik. Alrek was father to Agne, whose wife dispatched him with her own hands by hanging him on a tree with a golden chain near a place called Agnafit. His son, Ingjald, [...][8]

Agne is incorrectly called Hogne.[7] Unlike Ynglingatal, Historia Norwegiæ does not give Dagr as Agne's predecessor, but Alrekr. Instead Alrekr is Agne's predecessor and Agne is succeeded by Yngvi (incorrectly called Ingialdr[7]). The even earlier source Íslendingabók cites the line of descent in Ynglingatal and it gives the same line of succession as Historia Norwegiæ: xii Alrekr. xiii Agni. xiiii Yngvi.[9]

The location indicated by Snorri Sturluson as the place of Agne's death has a barrow called Agnehögen (Agne's barrow) in Lillhersby. The barrow was excavated by Oxenstierna and dated to c. 400.[10]

Agne married Skalf. [Group Sheet] [Family Chart]

Notes:

Dag the Wise or Dagr Spaka was a Swedish king of the House of Ynglings (dated to the 4th century by 16th-century historiographer Johannes Magnus). He was the son of Dyggvi, the former king. According to legend, he could understand the speech of birds and had a sparrow that gathered news for him from many lands. When the bird was killed on one of these trips, Dag invaded Reidgotaland (considering the date and location, apparently Gothiscandza), in order to avenge it. There he was ambushed by a thrall and killed.

The earliest two versions based on Ynglingatal, i.e. Historia Norwegiæ and Íslendingabók (see below) say that Dag was succeeded by his sons Alrekr and Eírikr who in their turn were succeeded by Dag's grandson Agne (in Historia Norwegiæ incorrectly called Hogne):

Historia Norwegiæ:
Cui [Dyggui] successit in regnum filius ejus Dagr, quem Dani in quodam vado, quod Sciotanvath vel Wapnavath dicitur, dum passeris injurias vindicare conaretur, publico bello occiderunt. Qui genuit Alrik; hunc frater suus Erikr freno percussit ad mortem. Alricr autem genuit Hogna

His [Dyggve's] son Dag succeeded to his throne; he was killed by the Danes in a royal battle at a ford named Skjotansvad, while he was trying to avenge the violence done to a sparrow. This man engendered Alrek, who was beaten to death with a bridle by his brother, Eirik. Alrek was father to Agne, [...]

Íslendingabók only lists the line of succession: x Dyggvi. xi Dagr. xii Alrekr. xiii Agni. xiiii Yngvi''.

However, in the Ynglinga saga, Snorri Sturluson gives Agne as Dag's son and successor, and the two brothers Alrekr and Eiríkr as his grandsons.

This is what Snorri tells of Dag:

Dagr hét son Dyggva konungs, er konungdóm tók eptir hann; hann var maðr svá spakr, at hann skildi fugls rödd. Hann átti spörr einn, er honum sagði mörg tíðindi; flaug hann á ymsi lönd. Þat var eitt sinn, at spörrinn flaug á Reiðgotaland, á bœ þann, er á Vörva heitir; hann flaug í akr karls ok fékk þar matar. Karl kom þar ok tók upp stein ok laust spörrinn til bana. Dagr konungr varð illa við, er spörrinn kom eigi heim; gékk hann þá til sónarblóts til fréttar, ok fékk þau svör, at spörr hans var drepinn á Vörva. Síðan bauð hann út her miklum ok fór til Gotlands; en er hann kom á Vörva, gékk hann upp með her sinn ok herjaði: fólkit flýði víðs vegar undan. Dagr konungr sneri herinum til skipa, er kveldaði, ok hafði hann drepit mart fólk ok mart handtekit. En er þeir fóru yfir á nökkura, þar sem heitir Skjótansvað eða Vápnavað, þá rann fram ór skógi einn verkþræll á árbakkann ok skaut heytjúgu í lið þeirra, ok kom í höfuð konungi skotit; féll hann þegar af hestinum ok fékk bana. Í þann tíma var sá höfðingi gramr kallaðr er herjaði, en hermennirnir gramir.

King Dygve's son, called Dag, succeeded to him, and was so wise a man that he understood the language of birds. He had a sparrow which told him much news, and flew to different countries. Once the sparrow flew to Reidgotaland, to a farm called Varva, where he flew into the peasant's corn-field and took his grain. The peasant came up, took a stone, and killed the sparrow. King Dag was ill-pleased that the sparrow did not come home; and as he, in a sacrifice of expiation, inquired after the sparrow, he got the answer that it was killed at Varva. Thereupon he ordered a great army, and went to Gotland; and when he came to Varva he landed with his men and plundered, and the people fled away before him. King Dag returned in the evening to his ships, after having killed many people and taken many prisoners. As they were going across a river at a place called Skjotan's [the Weapon's] Ford, a labouring thrall came running to the river-side, and threw a hay- fork into their troop. It struck the king on the head, so that he fell instantly from his horse and died. In those times the chief who ravaged a country was called Gram, and the men-at-arms under him Gramer.

Then Snorri quoted Ynglingatal (9th century):

Frák at Dagr
dauða orði
frægðar fúss
of fara skyldi,
þá er valteins
til Vörva kom
spakfrömuðr
spörs at hefna.
Ok þat orð
á austrvega
vísa ferð
frá vígi bar,
at þann gram
af geta skyldi
slöngviþref
Sleipnis verðar.
What news is this that the king's men,
Flying eastward through the glen,
Report? That Dag the Brave, whose name
Is sounded far and wide by Fame --
That Dag, who knew so well to wield
The battle-axe in bloody field,
Where brave men meet, no more will head
The brave – that mighty Dag is dead!
Varva was wasted with the sword,
And vengeance taken for the bird --
The little bird that used to bring
News to the ear of the great king.
Varva was ravaged, and the strife
Was ended, when the monarch's life
Was ended too – the great Dag fell
By the hay-fork of a base thrall!
The fact that Skjótansvað/Vápnavað appear both in Ynglinga saga and in Historia Norwegiæ's earlier summary of Ynglingatal but not in Snorri's later quotation from it, suggests that all of Ynglingatal was not presented by him.

Notes:

In Norse mythology, Dyggvi or Dyggve (Old Norse "Useful, Effective") was a Swedish king of the House of Ynglings. Dyggvi died and became the concubine of Hel, Loki's daughter. Dyggvi was succeeded by his son Dag the Wise. According to Snorre Sturlason, Dyggvi was the nephew of Dan, the eponymous anchestor of Denmark, through his sister Drott, and was the first to be called King by his family.

Snorri Sturluson wrote of Dygvvi's father Domar in his Ynglinga saga (1225):

Dyggvi hét son hans, er þar næst réð löndum, ok er frá honum ekki sagt annat, en hann varð sóttdauðr.

Dygve was the name of his son, who succeeded him in ruling the land; and about him nothing is said but that he died in his bed.

About Dyggvi's mother Snorri had more to say:

Móðir Dyggva var Drótt, dóttir Danps konungs, sonar Rígs, er fyrstr var konungr kallaðr á danska tungu; hans ættmenn höfðu ávalt síðan konungsnafn fyrir hit œzta tignarnafn. Dyggvi var fyrstr konungr kallaðr sinna ættmanna; en áðr váru þeir dróttnar kallaðir, en konur þeirra dróttningar, en drótt hirðsveitin. En Yngvi eða Ynguni var kallaðr hverr þeirra ættmanna alla ævi, en Ynglingar allir saman. Drótt dróttning var systir Dans konungs hins mikilláta, er Danmörk er við kend.

Dygve's mother was Drott, a daughter of King Danp, the son of Rig, who was first called "king" in the Danish tongue. His descendants always afterwards considered the title of king the title of highest dignity. Dygve was the first of his family to be called king, for his predecessors had been called "Drottnar", and their wives "Drottningar", and their court "Drott". Each of their race was called Yngve, or Yngune, and the whole race together Ynglinger. The Queen Drott was a sister of King Dan Mikillati, from whom Denmark took its name.

In his Ynglinga saga, Snorri Sturluson included a piece from Ynglingatal composed in the 9th century:

Kveðkat dul,
nema Dyggva hrör
Glitnis gná
at gamni hefr,
því at jódis
Ulfs ok Narfa
Konungmann
kjósa skyldi;
ok allvald
Yngva þjóðar
Loka mær
of leikinn hefr.
Dygve the Brave, the mighty king,
It is no hidden secret thing,
Has gone to meet a royal mate,
Riding upon the horse of Fate.
For Loke's daughter in her house
Of Yngve's race would have a spouse;
Therefore the fell-one snatched away
Brave Dygve from the light of day.
The Historia Norwegiæ presents a Latin summary of Ynglingatal, older than Snorri's quotation:

Hujus [Domar] filius Dyggui item in eadem regione vitæ metam invenit. Cui successit in regnum filius ejus Dagr [...]
Likewise Dyggve, his [Domar's] son, reached the limit of his life in that same region [Sweden]. His son Dag [...]

The even earlier source Íslendingabók also cites the line of descent in Ynglingatal and it also gives Dyggvi as the successor of Dómarr and the predecessor of Dagr: ix Dómarr. x Dyggvi. xi Dagr.
