Юдифь Баварская - Есфирь=Елена Волошанка? Красивая вторая жена Людовика Благочестивого, сына Карла Великого, спровоцировавшая смуту 830-834 годов во Франкском государстве, мятеж сыновей Людовика от первого брака против отца ("Авессаломы"?). Юдифь была дочерью Вельфа - возможно, "Вельф" здесь - слегка искаженное от "Велш", т.е. влахи, валахи, волохи, волошане - кстати, так называли даже итальянцев, т.е. латинян.

Её прямо сравнивают с Эсфирью, Иезавелью, Юдифью, обвиняют в колдовстве (астрологии?):

Scandals: Contemporary criticisms of Judith's role and behavior
...Agobard claimed that Judith’s extramarital affairs were carried out “first secretly and later impudently”.<4> Paschasis Radbertus accused Judith by associating her with the engagement in debauchery and witchcraft. of filling the palace with “soothsayers... seers and mutes as well as dream interpreters and those who consult entrail, indeed all those skilled in malign craft”
Characterized as a Jezebel and a Justina, Judith was accused by one of her enemies, Paschasius Radberus, of engaging in debauchery and witchcraft with her puported lover, Count Bernard of Septimania, Louis’ chamberlain and trusted adviser. This portrayal and image stands in contrast to poems about Judith.<2> The poems depict her as “a second biblical Judith, a Mary sister of Aaron in her musical abilities, a Saphho, a prophetess, cultivated, chaste, intelligent, pious, strong in spirit, and sweet in conversation”<2>
However, Judith also garnered devotion and respect. Hrabanus Maurus wrote a dedicatory letter to Judith, exalting her ”praiseworthy intellect”<9> and for her “good works”.<9> The letter commends her in the turbulent times amidst battles, wishing that she may see victory amidst the struggles she is facing. It also implores her “to follow through with a good deed once you have begun it”<9> and “to improve yourself at all times”. Most strikingly the letter wishes Judith to look to the biblical Queen Esther, the wife of King Xerxes I as inspiration and as a role model
Likewise, O queen, forever keep your eyes of your heart fixed upon Queen Esther as a model of dutiful and holy behaviour so that by equalling her holiness you might be able to climb from this earthly kingdom to the heights of the heavenly kingdom —Hrabanus Maurus

Про Кнуда Великого существует легенда как он пытался стать повелителем волн, поставив свой трон на берегу моря, но неудачно, волны не стали его слушаться, замочив его ноги и трон. После этого он повесил свою корону на распятие и не носил её больше. Поздние враждебные хроникёры объявили это проявлением безумия. Интересно, не тот же ли это сюжет, что и про Ксеркса, приказавшего высечь непослушное ему море или реку, что является, согласно НХ-реконструкции, отражением постройки Грозным Свияжска и взятия Казани 1552 года? Другое отражение этого сюжета - постройка Калигулой моста через залив, т.е. также попытка укрощения моря. В следующем 1553 году первый царь эпохи Грозного отходит от дел, став блаженным царём, т.е. также перестаёт носить корону.

Henry of Huntingdon, the 12th-century chronicler, tells how Cnut set his throne by the sea shore and commanded the tide to halt and not wet his feet and robes. Yet "continuing to rise as usual dashed over his feet and legs without respect to his royal person. Then the king leapt backwards, saying: 'Let all men know how empty and worthless is the power of kings, for there is none worthy of the name, but He whom heaven, earth, and sea obey by eternal laws.' He then hung his gold crown on a crucifix, and never wore it again "to the honour of God the almighty King".<95> This incident is usually misrepresented by popular commentators and politicians as an example of Cnut's arrogance.<96>

..It was allegedly Christian humility which made him reject his courtiers' flattery by demonstrating that even he could not stop the waves; later hostile chroniclers were to claim it showed madness.

...there are earlier Celtic parallels in stories of men who commanded the tides, namely Saint Illtud, Maelgwn, king of Gwynedd, and Tuirbe, of Tuirbe's Strand, in Brittany.<97>

http://ru.wikipedia.org/wiki/Майлгун_ап_Кадваллон (валл. Maelgwn ap Cadwallon, лат. Maglocunus, англ. Malcolm; ок. 480—547), также известный как Майлгун Гвинед или Майлгун Высокий (валл. Hir) — король Гвинеда примерно с 520 года.

...The Brythonic maglo- (from the proposed Proto-Celtic *magalos)

- что за Майлгун, может, Могол-Монгол? Гвинед от "венеды-венды"?

...The only contemporary information about the person is provided by Gildas, who includes Maelgwn among the five British kings who he condemns in allegorical terms in his De Excidio et Conquestu Britanniae. He says Maelgwn held a regional pre-eminence among the other 4 kings, going on to say that he overthrew his paternal uncle (Latin: avunculus) to gain the throne; that he had taken up life as a monk but then returned to the secular world; that he had been married and divorced, then remarried to the widow of his nephew after being responsible for his nephew's death; and that he was tall.<12><13>

- нехороший царь, убийца близких, не снова ли Грозный?

In his De Excidio et Conquestu Britanniae (English: On the Ruin and Conquest of Britain), written c. 540, Gildas makes an allegorical condemnation of 5 British kings by likening them to the beasts of the Christian Apocalypse as expressed in the biblical Book of Revelation, 13-2: the lion, leopard, bear, and dragon, with the dragon supreme among them.<16> He says that Maelgwn is the "dragon of the island", and goes on with a litany of moral accusations, in the process describing him almost as a regional high king over the other kings (the power-giving dragon of the Apocalypse). The Isle of Anglesey was the base of power of the kings of Gwynedd, so describing Maelgwn as the "dragon of the island" is appropriate.<12><13><17>

- уподоблен дракону Апокалипсиса, возможно, писания Гильды отражают страх османского=атаманского нашествия 15-16 вв.?

"На Кнуда Великого обычно указывают как на мудрого и успешного правителя Англии, несмотря на двоеженство и различные жестокости." - двоежёнство - не история ли Есфири-Елены там?
