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
