The Anglo-Saxon Period (c. 410-1066 CE) is the foundational era of English literature, characterized by a fusion of Germanic heroic culture and Christian themes. Key outputs include the epic *Beowulf*, poignant elegies like 'The Wanderer,' profound religious poetry such as 'The Dream of the Rood,' and seminal prose works like Bede's *History* and the *Anglo-Saxon Chronicle*, largely preserved in four major manuscripts.
The Anglo-Norman Period (1066-1350) was a trilingual era where literature flourished in Latin, French, and English. It was defined by the transmission of histories and legends (like Arthurian tales), the rise of the romance genre classified into 'Matters,' and significant works by figures like Geoffrey of Monmouth, Marie de France, and Layamon. This period preserved and adapted material, setting the stage for Chaucer's Middle English renaissance.
