I am preparing a new edition of the Mirror to Devout People, also known as the Speculum devotorum, for the Early English Text Society. A fifteenth-century life of Christ in the pseudo-Bonaventuran tradition, the Middle English Mirror was written by a Carthusian monk for a sister at the Bridgettine Syon Abbey. It draws on and reshapes numerous sources to guide the reader through her spiritual life, while referencing the ongoing translation debates in late-medieval England. Through its discussion of authorization and translation, the Mirror becomes a central text in the formation of late medieval English devotional culture.
