Leonardo's Civil Bridges

Within both aesthetic and history fields, civil engineering occupies a privileged place among arts whose manifestations are based on drawing. In this work, Leonardo’s creativity concerned with civil bridges proyects, have been studied. Leonardo designed ten bridges: eight of them intended for military porposes and only two were purely planned for civil functionaly - “Ponte sul corno d’oro”, infolio 66, manuscript L; and “Ponte a due piani”, represented in the Manuscript B at the Institute of France, infolio 23. There can be no doubt about Leonardo’s intentions when he started on designing these two bridges: his genious for creativy focused on providing both singulary and functionaly to the structures: they should be admired and utilized at the same time, a monument for civil society to be used.The work presented here attemps to make an scientist-historical trip along these Leonardo’s bridges, highlighting their technical, geometrical and aesthetic characteristics, as well as emphasizing Leonardo’s human, scientist and artistic nature.

Aplicación de nuevas tecnologías en la Arqueología de la Guerra Civil Española: Los Yesares, Pinto (Madrid. Application of new technologies in archeology of the Civil War:The Yesares, Pinto (Madrid.

ABSTRACT: The surveys carried out in the municipality of Pinto (Madrid) have enabled us to locate various structural remains linked to the military operations that took place around the capital during the Spanish Civil War (1936-1939). In order to identify and record them, surveys were complemented with the use of GPS and air photographs from different time periods. Afterwards, and in collaboration with researchers from various universities, further methods aimed at generating a complete special representation of the area were applied directly to one of the sites which produced the best results, known as "los Yesares". These methods include topographic mapping that resulted in cartographic material at different scales, the photographic recording with flying Unmanned Aerial Vehicles, and the use of land scanners and GPS-corrected photogrammetrics with which to obtain 3D models.
