In this short poem from the 10th century Exeter Book, the single largest collection of Old English poetry, the poet hints at the tragic lives of five figures from Germanic heroic legend, before telling of his own. The five figures are:
Wayland the Smith,1 who was captured by the tyrant Nithad and forced to make jewelry for him and his family. He took revenge by raping
Nithad’s daughter, Beadhild. The child born from this act was Woody (OE Wudga), an obscure hero.
Mathild (Matilda), the protagonist of poorly attested love tragedy.
Thedric (Theoderic) the Great, who ruled over the Goths before
Erminric (Ermanaric). His cruelty and wolfishness may refer to his murder of Swanhild or Sunhilda, attested both in Jordanes and in much later Norse poetry.
After shortly describing these five lives, the poet reflects on the fickleness of the World (6). He then shares his own tragedy as an ousted court-poet (7).
His name, Déor, is the ancestor of modern English deer, and can mean this in Old English as well, but it can also mean ‘beast, animal’. It is not otherwise known as a personal name, but in Norse heroic poetry the hero Siward (Sigurðr) at one point calls himself gǫfugt dýr ‘noble beast/deer’.2 Regardless of whether the story is fictional, the feelings expressed are genuine and the poem is very fine. I have attempted to render it as best I can in a literal translation that retains the style and feel of the original.
Deer.
1. Wayland with worms his exile experienced; the one-minded earl hardship did suffer; had him for fellows sorrow and longing, winter-cold exile. Woes he often found, since Nithad on him fetters did lay, hard sinew-bonds on the better man. That passed over; this may likewise. 2. For Beadhild was not her brothers’ deaths on her heart so sore as her own thing: that she clearly had understood that she was pregnant. Never could she readily think out what she should do about it. That passed over; this may likewise. 3. That for Mathild many, we have heard, bottomless [troubles] arose, for Geat’s beloved, that the sorrowful love her of sleep all deprived. That passed over; this may likewise. 4. Thedric owned for thirty winters the fort of the Meerings; that was to many known. That passed over; this may likewise. 5. We have learned of Erminric’s wolven nature. He ruled widely the folk of the realm of the Gots—that was a grim king! Sat many a man by sorrows bound, woes in his thoughts, wished aplenty that that kingdom might be overcome. That passed over; this may likewise. 6. One sits grieved with sorrow, of blessings bereft; his heart darkens; to himself he thinks that endless must be his share of hardships. He may then think that through this world the Wise Lord turns coat aplenty. To many an earl honour he shows, sure success—to another a share of woes. 7. This of myself I wish to say, that for a while I was the Heedenings’s shop, dear to their lord—Deer was my name. I had for a great many winters a good retinue, a true bread-giver, until Harrend now, the lay-crafty man, the land-right has won, that to me the shelter of earls of yore did grant. That passed over; this may likewise.

The story of Wayland is told more at length in the Norse Lay of Wayland, found in the Poetic Edda. See my translation.
Fáfnismǫ́l 2. See my post on the Stag as a heroic symbol.
I wonder if already at that time Wayland and Beadhild were connected to Wudga
Really interesting to see the connections between these characters as recorded by the English, Roman history, and other Germanic languages. Ermenaric has a brief mention by Ammianus as well, who was a contemporary, yet Ammianus (along with later Jordanes) seems to speak of him more positively whereas later Germanic legend seems to depict Ermenaric more negatively. Makes me think the Germanic legendary ‘storybook’ wasn’t at all reliant on Roman histories and independently preserved these traditions
You might be interested to learn that someone has set this poem to a melody on the Anglo-Saxon lyre. I don't think this is what a scop would have sounded like, for various reasons, but that doesn't stop me coming back to listen.
