Marguerite de Navarre (1492–1549), sister of François i, was a protector of evangelical reformers and a prolific writer; this Companion celebrates both her literary and her religious contribution. The versatility of her writing, which ranges across theatre, poetry and a collection of short stories, is explored in seven of the volume's nine essays by a collection of fine seiziémistes. These essays are framed by the editors' introduction which presents a valuable, streamlined account of her life and religious significance, and by two essays (Reid and Le Gall) which offer contrasting interpretations of her religious belief and activities – thereby also contributing fruitfully to the continuing debate about her faith – but converge in their sensitivity to the complexity of the relationship between her literary works and her religious beliefs. These three contributions provide an admirable context in which to review the literary texts: the Neo-Platonism of the spiritual poetry and the Heptaméron (Ford); the earlier and later meditative poetry of the Miroirs (Garnier and Pantin); the poetic dialogues of mourning, the Dialogue en forme de vision nocturne and La Navire (Leushuis); the devotional poem Les Prisons, with its ‘polyphonic’ (p. 235) exploration of the quest for God's love (Skenazi); the Chansons spirituelles, in which death becomes beautiful (Miernowski); the biblical and non-biblical plays (Millet); and the short stories and discussions that form the Heptaméron (Ferguson and McKinley). Each essay highlights the different ways in which Marguerite de Navarre's spirituality and ‘practical’ (p. 22), non-dogmatic theology imbue all her writing, even the more secular Heptaméron, and the emphasis that each places on the plurality of co-existing interpretations chimes both with the author's theological stance and with the ways in which her writing repeatedly seeks to invite the reader to reflect, question and interpret afresh. The essays are both scholarly and accessible, and variously refresh existing approaches or offer new insights into such questions as the place of Neo-Platonism (Ford) and Petrarchism (Leushuis) in the texts. The whole is more than the sum of its illuminating parts; recurring emphases across the essays, together with the initial focus on Marguerite de Navarre's religious belief and significance, make for an enlivening review of her writing and of her exploration of the resources of her chosen genres as means to engage the reader's potential for contemplation and reflection. The volume enhances our sense of the potency of the author's spirituality in all of the writing and extends our understanding of this ‘supple religious thinker’ (p. 26).
