In the framework of Archaeological Research, and the archeology of lived spaces, the object of study is metrology applied in composition of religious architecture in Egypt. The analysis of certain buildings, their proportions, geometry, construction purpose, and measutrement units in which they were designed, allows us to give an idea of the liturgy that took place in the spaces, and their mathematical conception.

The objective is the determination of geometric and metrological relations in architectural models and the module used in the initial project of the buildings. The study and data collection of religious buildings, tombs and temples of ancient Theban necropolis, is completed with plans. The measurements systematization and buildings modulation makes possible to establish common compositional parameters, with a module determined by the measurement unit used

The measurement system corresponding to that period, was the Egyptian royal cubit. The analysis of units measurements, used in architectural design, provides exact numbers on buildable spaces dimensions. It allows establishing proportional relationships between them, and finding a geometric composition module, on which the original project was based. This responds to a philosophical and functional concept of projected spaces.

The analysis of the place chosen for location responds to the religious idea of ancient Egyptian thought, sacred topography. The genesis of the initial project indicates the purpose of the building itself, whether it was intended for religious worship, funerary purposes, or specific rituals.

The patterns and measurements of the constructions respond to religious and philosophical concepts that evolve in each era and period. The architectural typologies adapt to beliefs, since the design of the buildings is directly linked to these proportions and ritual geometry.

These spaces are considered in research, to try to understand original functioning, their changes and evolution in subsequent centuries.

The late period of Egyptian civilization was a catalyst for cultures, due to Greek and Roman influences and the appearance of Christianity, which shook the powerful existing beliefs, adapting to new currents what had been established for millennia. In architecture it meant a reuse of spaces, iconography and architectural models, Ancient necropolises become refuges for ascetics and hermits, grandiose temples were transformed into convents and monasteries, and other pharaonic constructions were forgotten and buried by sand. The initial measurements and proportions, which obeyed strict magical and liturgical concepts, were clouded by new uses.

In the field of heritage rehabilitation and restoration, knowledge of these patterns helps in excavation, reconstruction and restoration of construction elements. The correct use of metrology contributes to the identification of possible work areas, helping to locate where the damaged or missing areas are. Also in restoration projects, metrology is useful for reordering and locating decontextualized parts of buildings. The translation of measurements taken in the current International System to the measurements in which the original project was conceived, allows understand its conceptual purpose and its functionality, which makes easier to carry out archaeological intervention. Knowledge of architectural typologies, the spaces distribution and their original measurements is essential to optimize work methods in archaeological excavations.
