In Pharaonic Egypt, multimodal communication is found in a variety of forms and functions. This applies in particular to text-image-composites on temple walls and in tombs, but also to less prominent media such as rock inscriptions or petroglyphs. As such, these composites are well known in the field of Egyptology and have been intensively studied from a cultural-historical perspective. The semiotic analysis of their form and function as acts of multimodal communication, however, has gained so far only minor attention, although a thorough and theoretically informed investigation from this angle would yield a deeper understanding of the communication practices and the cultural knowledge of Pharaonic Egypt. Since the hieroglyphic-Egyptian writing system and the specific schemes of Egyptian pictorial art share common design features and principles, a semiotically grounded analysis would furthermore enrich the general discussion of the theory and modelling of multimodal communication, which at this point mostly focusses on text-image-composites from cultures using alphabetical writing systems. The Corpus of Ancient Egyptian Multimodal Communication (CAEMmCom) is a starting point for establishing this field of research in Egyptology. It integrates a variety of methods and theories of multimodal communication, which have been adapted for the analysis of Ancient Egyptian material. In our talk, we will present the overall design of the corpus, including discussion of the data- and metadata-structure, the software used (HyperImage) and the underlying database concept, which will enable quantitative analysis of data in the future.
