The Old English poem is one of many retellings of the Holofernes–Judith tale as it was found in the Book of Judith, still present in the Catholic and Orthodox Christian Bibles.
Though it is certain that the poem is a derivative of the Book of Judith, still present in the Roman Catholic Bible, its authorship and year of origin remain a mystery.
The poem is incomplete: the version in the manuscript is 348 lines long, divided in three sections marked with the numbers X, XI, and XII.
Some scholars use the Apocryphal Judith as evidence for the text missing, while others refute this as unreliable as the Old English poet is not loyal to this source.
Judith is depicted as an exemplar woman, grounded by ideal morale, probity, courage, and religious conviction.
Although Judith kills a man, she appears to be doing God's will; Holofernes, while described to some extent as a standard military leader in the Beowulfian vein, is also cast as a salacious drunk and becomes monstrous in his excess.
Portraying the epitome of Germanic heroism, Judith was likely composed during a time of war as a model for the Anglo-Saxon people.
In a letter, Ælfric wrote: þeo is eac on English on ure wisan iset eow mannum to bisne, þet ge eower eard mid wæpnum beweriæn wið onwinnende here, meaning "It is also set as an example for you in English according to our style, so that you will defend your land with weapons against an attacking force".
Thus, the seeming paradox of a woman as the military leader of her people is not just the result of a difficulty in adapting a biblical story to a Germanic heroic idiom.”[6] There are also key narrative details: the Old English Judith, after severing the head of Holofernes, proudly displayed his head to her Hebrew army and led them into a victorious battle against the Assyrians.
In contrast, in the Book of Judith, the Assyrians simply fled Bethulia after discovering the deceased body of Holofernes.
[8] The consensus held by modern scholars allocates Judith to the authorship of Cynewulf, though several opposing theories have been proposed.
