Middle-earth! Do you know about the Hobbits? Of course you know it. We all saw at least one excerpt from a film "The Lord of the Lambs". But who really knows the creator of these worlds? Fans of J.R.R. Tolkien, the British writer, may be delighted. The Bnf opens the largest retrospective ever organized on the protean work of J.R.R. Tolkien, successful author of fantasy literature and brilliant Oxford professor. Produced in collaboration with the Tolkien Estate and the Tolkien family, the Bnf partnered with the Bodley Library at Oxford University, which hosted the exhibition "JRR Tolkien: Maker of Middle-Earth" from June to October 2018. The 300 pieces on 1000m² on display highlight both the man and his work. For the first time in France, many manuscripts often illustrated by the English illustrator Alan Lee and original drawings by Tolkien, with many details, diagrams are presented. The exhibition is seen as an invitation to travel, to the heart of Tolkien's imaginary geography, revealing his landscapes, peoples and languages, all invented by this professor of medieval languages and literature at Oxford. The first part of the exhibition offers a dive into Middle-earth, from the County to Mordor, then beyond, into Valinor. At the same time, a selection of exceptional pieces from most of the BnF collections provides a context for this artistic and literary creation. The exceptional presentation of 4 tapestries recently woven from Tolkien's watercolours by the Cité internationale de la tapisserie d'Aubusson enriches the tour of this amazing exhibition.
