From the preparation of the Council to its conclusions. All the protagonists and the proceedings of a memorable historical event. The end of 2015 has marked the fiftieth anniversary of the conclusion of the Second Vatican Council. Subsequently the ‘Foundation for Religious Sciences in Bologna’, then directed by Giuseppe Alberigo, published a series of fundamental volumes on the Council. Fifty years later Jaca Book and the Foundation for Religious Sciences, now directed by Alberto Melloni, have decided to produce the first illustrated Historical Atlas of the Second Vatican Council using the Foundation’s archives and the best photographic archives available. Participants from all over the world attended the Council, and in this volume the reader will recognize its protagonists, the way in which their work took place, and aspects of their daily life. The reader will be able to follow the progress of the works leading to the Council’s great ‘declarations’ and ‘documents’, and the way the conciliar texts were voted, revised, prepared for the final voting, as well as the final promulgation. A work rich in information, documents and illustrations that bring the reader into the atmosphere of an extraordinary historical moment full of hope for the Church and for humanity. A strong link with Pope Francis who finds in Vatican II the roots of a great work still to be done. An important work for all scholars who will have access to data and facts which are otherwise difficult to access. A work targeted at a large audience as well, which will have an insight into an unforgettable experience.
