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".
Welsh mythology Welsh mythology consists of both folk traditions developed in Wales, and traditions developed by the Celtic Britons elsewhere before the end of the first millennium. Like most predominately oral societies found in the prehistoric Britain, Welsh mythology and history was recorded orally by specialists such as druids (Welsh: "derwydd" ). This oral record has been lost or altered as result of outside contact and invasion over the years. Much of this altered mythology and history are preserved in medieval Welsh manuscripts which include the Red Book of Hergest, the White Book of Rhydderch, the Book of Aneirin and the Book of Taliesin. Other works connected to Welsh mythology include the ninth century Latin historical compilation "Historia Brittonum" ("History of the Britons") and Geoffrey of Monmouth's twelfth-century Latin chronicle, "Historia Regum Britanniae" ("History of the Kings of Britain") as well as later folklore such as the 1908 "The Welsh Fairy Book" by William Jenkyn Thomas.
