   • 11th century, Cnutonis regis gesta sive encomium Emmae reginae, book 2, chapter 16; in: Georgius Heinricus Perts (editor), Scriptores rerum germanicarum in usum scholarum ex monumentis Germaniae historicis recudi fecit: Cnutonis regis gesta sive encomium Emmae reginae, 1865, p. 23f.:

     Sed abnegat illa, se unquam Chnutonis sponsam fieri, nisi illi iusiurando affirmaret, quod nunquam alterius coniugis filium post se regnare faceret nisi eius, si forte ille Deus ex eo filium dedisset. [...] Placuit ergo regi verbum virginis, et iusiurando facto virgini placuit voluntas regis;"

     But she refused ever to become the bride of Cnut (Knútr), unless he would affirm to her by oath, that he would never set up the son of any wife other than herself to rule after him, if it happened that God should give her a son by him. [...] Accordingly the king found what the virgin said acceptable and when the oath had been taken, the virgin found what the king said acceptable.^[1]
