First edition, published posthumously, although the preface was written by Heuzey in 1918. As he contemplated the problems of the Balkans as background to the War and the problems of peace, he recovered the notes of a journey he had made in 1858 through Thessaly and other parts of European Turkey. Hubert Pernot and Heuzey’s grandson decided to publish the manuscript as no. 5 in the series of the ‘Collection de l’Institut Néo-Hellénique’.
