Armes Prydein
Armes Prydein (Welsh pronunciation: [ˈarmɛs ˈprədəin], The Prophecy of Britain) is an early 10th-century Welsh prophetic poem from the Book of Taliesin. In a rousing style characteristic of Welsh heroic poetry, it describes a future where all of Brythonic peoples are allied with the Scots, the Irish, and the Vikings of Dublin under Welsh leadership, and together succeed in driving the Anglo-Saxons from Britain forever.
