The author of this brilliant and monumental work is a Swedish archaeologist, whose name will be well known to those who have followed with the greatest interest his outstanding, and, from both the archaeological and historical point of view, so fruitful and important excavations in Tonkin and North Annam between 1934 and 1939. The results have appeared, from time to time, in Bulletin de l'École Française d'Extrême-Orient, Cahiers de l'École Française d'Extrême-Orient, and the Illustrated London News. Professor Janse's work was carried out under the auspices of the École Française d'Extrême-Orient, Hanoi, the Museums of Paris and of the Harvard-Yenching Institute. This fine book contains 113 pages in the text and 169 beautiful plates, showing a great number of the objects found, besides several clear and instructive plans of the most characteristic of the brick-built tombs excavated. There are also 56 figures in the text.
