La Bataille Loquifer, edited by Monica Barnett, is a critical edition of a 13th-century French epic poem from the Cycle de Guillaume d'Orange. The text follows the adventures of Renoart au Tinel, a character who transforms from a comic figure in earlier epics to a central heroic protagonist. The poem recounts Renoart’s battle with the giant Loquifer and other supernatural elements, blending chivalric themes with the fantastical.

This edition is based on the most complete version from the Bibliothèque Nationale de France, with additional material from other manuscripts, including the Arsenal/Boulogne and prose versions. Barnett meticulously reconstructs the text and compares various manuscript traditions, highlighting key differences in narrative events, including the rescue of characters by magical birds and Renoart’s journey to Avalon.

Barnett's work provides deep insight into the historical and literary significance of the Bataille Loquifer within medieval French literature, offering a comprehensive analysis of its themes, versification, and manuscript history. This edition is essential for scholars of medieval romance, epic poetry, and manuscript studies, preserving and presenting a critical piece of the rich chanson de geste tradition.
