Collective work with international dimension, The Marguerite Yourcenar Dictionary offers in 325 entries an analytical presentation of the work, the intellectual figure, the public positions, highlights of the existence of Marguerite Yourcenar (1903-1987). French woman of letters born in Belgium and naturalized American, it is illustrated during six decades in all the literary genres while doubling its work by an intense epistolary activity. In withdrawal of modernity embodied by surrealism, existentialism and the nouveau roman, the first woman elected to the French Academy, however, moves many uses and is in phase with XXI e century which it announces certain cultural developments: the play between fiction and non-fiction, the renewal of self-writing outside the autobiographical model, the ecological claim of which it counts among the pioneers, the demand for a world literature to which this eternal traveler combines an ideal of universality.--Translation of page 4 of cover by Honoré Champion.
