Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Some of the highest and widest vault constructions produced in the Middle Ages are located in the Mediterranean area. Outstanding buildings with remarkable vaults and buttressing, such as the Cathedral of Majorca, are evidence of a lively technology transfer and contemporary developments. International experts trace the complex processes of Medieval design and construction. They research structural patterns in the processes involved, analyze building methods, and relate their findings to historic documents. The approach of combining field research with the study of literary sources provides a fresh look at the impressive monuments and shines new light on technological advances and construction technology of the time.
