The book “Mémoire historique sur le Dôme du Panthéon Français” summarizes four chapters and one conclusion. At the beginning of the book is a very short table of contents, which lists the most important points, with which the book is concerned. The book deals with the construction and some accidents that happened in the Panthéon in Paris. The book begins with a preface and ends with a revealing conclusion by Jean Baptiste Rondelet. The four chapters in between have sub-chapters which have a descriptive title. The book has ten detailed plans of the Cathedral, which can be found at the end of the book. In the rest of the book there is only text and no explanatory illustrations. They are foldable and thus almost double the size of the book. This larger format makes it easier to view the pictures. The book has 119 pages and includes the title page as well as the last pages of the book. The dimensions of the book are 280 x 220 x 20 mm. The traditional format of the book is “Quarto”. The first letter of each chapter has an ornate capital letter. In general the book is in a very good condition and still very legible. However, some pages are torn and have some folds.
