What book contains a poem which, along with "Beowulf" and the "Anglo-Saxon Chronicle", preserves a legendary list of the kings of the Angles?
Widsith Widsith is an Old English poem of 143 lines. The poem survives only in the Exeter Book, a manuscript of Old English poetry compiled in the late 10th century containing approximately one sixth of all surviving Old English poetry. Widsith is located between the poems "Vainglory" and "The Fortunes of Men". Since the donation of the Exeter Book in 1076, it has been housed in Exeter Cathedral in southwest England. The poem is for the most part a survey of the people, kings, and heroes of Europe in the Heroic Age of Northern Europe: see Tribes of Widsith.
White Book of Rhydderch The White Book of Rhydderch (Welsh: "Llyfr Gwyn Rhydderch", National Library of Wales, Peniarth MS 4-5) is one of the most notable and celebrated surviving manuscripts in Welsh. Mostly written in southwest Wales in the middle of the 14th century (c. 1350) it is the earliest collection of Welsh prose texts, though it also contains some examples of early Welsh poetry. It is now part of the collection of the National Library of Wales, having been preserved in the library at Hengwrt, near Dolgellau, Gwynedd, of the 17th century antiquary Robert Vaughan, who inherited it from the calligrapher John Jones and passed it to his descendants. The collection later passed to the newly established National Library of Wales as the Peniarth or Hengwrt-Peniarth Manuscripts.
