The Ulster Cycle, formerly known as the Red Branch Cycle, is a body of medieval Irish heroic legends and sagas of the Ulaid. It is set far in the past, in what is now eastern Ulster and northern Leinster, particularly counties Armagh, Down and Louth. It focuses on the mythical Ulster king Conchobar mac Nessa and his court at Emain Macha, the hero Cú Chulainn, and their conflict with the Connachta and queen Medb.The longest and most important tale is the epic Táin Bó Cúailnge (Cattle Raid of Cooley). The Ulster Cycle is one of the four 'cycles' of Irish mythology and legend, along with the Mythological Cycle, the Fianna Cycle and the Kings' Cycle.

The Dream of the Rood is one of the Christian poems in the corpus of Old English literature and an example of the genre of dream poetry. Like most Old English poetry, it is written in alliterative verse. The word Rood is derived from the Old English word rōd 'pole', or more specifically 'crucifix'. Preserved in the tenth-century Vercelli Book, the poem may be as old as the eighth-century Ruthwell Cross and is considered one of the oldest extant works of Old English literature.
