What is the title of Tolkien's published translation and commentary on the Old English poem Beowulf?

Tolkien’s published translation and commentary on Beowulf is titled Beowulf: A Translation and Commentary.

Tolkien worked on his Beowulf translation during the 1920s, drawing on his expertise as an Old English scholar. The book presents his prose translation alongside commentary that discusses the poem’s language, imagery, structure, and cultural background. It was edited by his son Christopher Tolkien and published posthumously in 2014.

The volume also includes “Sellic Spell,” Tolkien’s imaginative reconstruction of a possible folktale behind the Beowulf story, and two versions of “The Lay of Beowulf.” These materials show how Tolkien combined philological research with creative writing.

The title is often confused with “Beowulf: The Monsters and the Critics,” Tolkien’s influential 1936 lecture and essay. That work argues that the monsters are central to the poem’s design; it is not the title of his later translation. Beowulf itself is an Old English heroic poem about a Geatish warrior who fights Grendel, Grendel’s mother, and a dragon.
