The project concerns the publication of a book, "På besök i stormaktstidens Sverige", published by Natur & Kultur. In the book, I recount and comment on the travel accounts from the 17th century left by a total of eleven French-speaking visitors to Sweden, ten French and one Swiss, and which in several cases have never before been recognized in Swedish research. Together, these accounts provide a detailed, partly new and in-depth picture of Sweden at the time and of how conditions were perceived by travelers from a country that, regardless of religious differences, was a political ally. "A Visit to Sweden in the Age of Great Power" is also in many ways a continuation and expansion of my book "The Journey of the French Chamberlain", which was published in 2013 with substantial support from the Torsten Söderberg Foundation. Nearly forty illustrations, some of which have rarely or never been reproduced in historical literature, contribute to the understanding of the text. They should be reproduced in the best possible technical quality, and my application is for a contribution to ensure good image reproduction.
