The Anglo-Saxon Chronicle (ASC) is the name commonly given to the group of texts containing annals which record the history of Anglo-Saxon England. Its seven manuscripts – referred to in scholarship by the letters A-G (quoted below behind the annal number) – include a number of poems that commemorate important moments in Anglo-Saxon history. That these Chronicle poems have generally received little scholarly attention is due to their allegedly marginal status within the overwhelmingly prose content of the ASC. Like most Anglo-Saxon poetry, they are transmitted anonymously, although three poems (annals 959-DEF, 1011-CDEF, 975-DE) have been attributed to Wulfstan, archbishop of York (1002-23).
