By studying the vocabulary of the millers, millwrights and blacksmiths of the past who were active in northern France, the author preserves an immense lexical treasury, one that is especially important since the region has always been renowned for its production of oil and flour. This lexicon is an indispensable complement to traditional dictionaries, which have devoted little attention to technical vocabulary: more than twenty per cent of its definitions and words are new. It provides clear and precise definitions, examples that are as diverse and detailed as possible, and numerous illustrations, which will interest not only the specialist in mills but any researcher who, in working with archives, is confronted with technical texts.Through the varied entries in this dictionary, we see a new image of the mill, one that has evolved over the centuries and that commands our admiration. Here at last is a dictionary that gives a voice to manual workers over the centuries, it is they who have freed us from the heaviest of our labours and indirectly facilitated the blossoming of intellectual life.
