Before the murder of the king became generally known, Rosamund and her adherents--for she had many--secured and concealed the treasures of the Crown; and when the nobles bade her marry a man to succeed their king, who had left no heirs, she declared that she preferred Helmigis.
[Sidenote: Death of Rosamund.] The Langobardian nobles indignantly refused to recognize an armor-bearer as their king, and Rosamund, fearing their resentment, fled by night with her treasures, and took refuge with Longinus, viceroy of the Eastern emperor, who was intrenched in Ravenna.
Captivated by the fugitive queen's exquisite beauty, no less than by her numerous treasures, Longinus proposed that she should poison Helmigis, and marry him.

Rosamund obediently handed the deadly cup to her faithful adorer; but he drank only half its contents, and then, perceiving that he was poisoned, forced her, at the point of his sword, to drink the remainder, thus making sure that she would not long survive him.
Longinus, thus deprived of a beautiful bride, managed to console himself for her loss by appropriating her treasures, while the Langobardian scepter, after having been wielded by different kings, fell at last into the hands of Rother, the last influential monarch of a kingdom which Charlemagne conquered in 774.
[Sidenote: Rother.] Rother established his capital at Bari, a great seaport in Apulia; but although his wealth was unbounded and his kingdom extensive, he was far from happy, for he had neither wife nor child to share his home.
Seeing his loneliness, one of his courtiers, Duke Berchther (Berchtung) of Meran, the father of twelve stalwart sons, advised him to seek a wife; and when Rother declared that he knew of no princess pretty enough to please his fastidious taste, the courtier produced the portrait of Oda, daughter of Constantine, Emperor of the East.

Rother fell desperately in love with this princess at first sight.

In vain Berchther warned him that the emperor had the unpleasant habit of beheading all his daughter's would-be suitors; Rother declared that he must make an attempt to secure this peerless bride, and was only with great difficulty persuaded to resign the idea of wooing in person.
When Berchther had prevailed upon him to send an imposing embassy of twelve noblemen, richly appareled, and attended by a large suite, Rother asked who would undertake the mission.

All the warriors maintained a neutral silence, until seven of Berchther's sons volunteered their services, and then five other noblemen signified their readiness to accompany them.
To speed them on their way, Rother escorted them to the port, and, standing on the pier, composed and sang a marvelous song.
