Vectorialization practices of the image drawing of the floor mosaics of the Basilica of Nativity in Bethlehem

Abstract

The research deals with the different image vectorialization techniques for the development of reliable drawings on mosaic systems. Following the restoration of the floor mosaics of the Basilica of the Nativity in Bethlehem, surveys were conducted with digital technologies that produced a 3D database on considerable mosaic surfaces. The problem of the graphic representation, linked to the drawing of these systems, concerns both the optimization of the methodological processes to the advantage of a more performing drawing activity, and the definition of the appropriate languages to satisfy requirements related to the documentation and the work restoration. Technical drawers have worked alongside restorers to produce technical drawings and a model from which interact with the mosaic system, developing an informative model that can facilitate construction activities and, at the same time, enhance the entire artwork.
