By virtue of their professions, archaeologists excavate, observe, develop hypotheses, and make comparisons, while architects design and define construction systems: both work within a common framework comprised of elements from the history of styles, places, and uses. The northern church of Baouît is one example of the convergence of these two professions. The sum of data collected during excavations at the beginning of the 20th century and from 2003 to 2007 (measurements and dimensions of the elements found, as well as collections of photographic images) made it possible to establish a common research framework between the team of archaeologists from the Louvre Museum, on the one hand, and Master's students, their teachers, and researchers from the EVCAU laboratory (Virtual Space for Architectural and Urban Design) of the École nationale supérieure d'architecture Paris-Val de Seine, on the other. This research project involved offering architecture students a two-stage project on modeling the church: first, creating a model of the existing structure, in other words, the church's archaeological state—an essential step for developing, in a second stage, a model according to which the church could be reconstructed. This second stage was intended to address a long-standing architectural question: how did the Copts of the 8th to 11th centuries roof their churches? It was also intended to allow for a reconstruction of the building's decoration, including its paintings, sculptures, and woodwork. The use of digital techniques was essential from the outset. The impossibility of a physical reconstruction led to the use of a virtual reconstruction using three-dimensional digital models. The 3D model of the church is based on the DWG format plan of the detailed survey of the north church excavated during the 2003, 2004, and 2005 campaigns (architects RW Boutros and B. Maurice). The dimensions of the columns, walls, niches, most of the slabs, and decorative elements are included. The heights used are those recorded in the surveys of the elements still existing during these campaigns. By comparison with photographs taken during the campaigns of J. Clédat, É. Chassinat, and C. Palanque, these measurements allowed for a more precise determination of the heights of the architectural elements found at the beginning of the 20th century. The dimensions of the broken but complete shafts of two of the columns allowed for a more precise determination of the church's height. The dimensions of architectural and decorative elements displayed at the Louvre Museum (Baouît Room) were also used. Once established, these digital models facilitate the possibility of varying hypotheses, allow for flexibility in the proposed assemblies, and support collaborative work, the exchange of ideas, and discussions. Thus, thanks to the architects' ability to propose hypotheses drawn from the history of styles, significant work was done on the church's roof and the definition of constructible, physically stable architectural structures, consistent with the remains and the parallels identified, and on the possible evolutions of this roof.⁴ The reconstruction of a sculpted niche and its placement within the church model demonstrated the usefulness of the method in the case of elements dispersed across three locations.⁵ The digital anastylosis most closely linked to the observations and discoveries during the various excavations is that which led to the reconstruction of the pulpit, for which the students had to create their digital model under specific geometric constraints. This type of collaboration enables the training of architects capable of critically and analytically interpreting a specific environment. The training resulted in the discovery of issues related to architectural and archaeological heritage, the study of diverse documentary sources, the learning of working methods used by archaeologists and historians, the development of hypotheses, and the search for coherent solutions. For the archaeologists, the resulting digital simulations allowed them to verify the consistency of the surveyed elements and to validate, in structural terms, the assumptions regarding the covering. These digital models were also used as the basis for multimedia public communication and virtual tours.
