Graphic symbols i.e. graphic entities drawn as a visual unit in a written text and representing something other or something more
than a word of that text are the research object of the NOTAE project, which investigates them in the documentary practice of the late Roman State and Post-Roman Kingdoms (400-800 AD). While research results from the project are stored by filling forms resulting from the analysis
of ancient documents, we argue that the availability of a navigable knowledge graph can ease the work of researchers at finding non trivial
implications in data. In this paper, we propose a first version of the NOTAE Knowledge Graph, and we outline future works and possible synergies.
