What book contains a poem which, along with "Beowulf" and the "Anglo-Saxon Chronicle", preserves a legendary list of the kings of the Angles?
Kings of the Angles The Angles were a dominant Germanic tribe in the Anglo-Saxon settlement of Britain, and gave their name to the English, England and to the region of East Anglia. Originally from Angeln, present-day Schleswig-Holstein, a legendary list of their kings has been preserved in the heroic poems "Widsith" and "Beowulf", and the "Anglo-Saxon Chronicle".
King Horn King Horn is a Middle English chivalric romance dating back to the middle of the thirteenth century. It survives in three manuscripts: MS. Harley 2253 at the British Library, London; MS. Laud. Misc 108 at the Bodleian Library, Oxford; and MS. Gg. iv. 27. 2 at the Cambridge University Library. It is also presumably based on the Anglo-Norman story "Romance of Horn" (1170). The story was retold in later romances and ballads, and is considered part of the Matter of England. The poem is currently believed to be the oldest extant romance in Middle English.
