Atlantic Rock Art is a rock art tradition which includes emblematic motifs such as cup-marks, cup-and-rings and lines, known to several countries on the Atlantic seaboard. Design and Connectivity springs from an inter-regional study of this tradition, based on an original and innovative methodology applied to an empirical dataset. The project builds on Richard Bradley's work, investigating differences and similarities in Atlantic Art over study areas in five countries: Scotland, England, Ireland, Spain and Portugal. It applies a multi-scalar methodology developed under the principles of Relational Ontology and Assemblage Theory, providing a dynamic perspective on the empirical data. A thorough categorical scheme was scrutinised using a Presence/Absence Matrix, spatial analysis (fieldwork and GIS) and the development of Social Network Analysis (SNA) to relate and explore the relationships and connectivity between study areas. Concepts of developmental psychology support the idea of intentional teaching and cultural transmission.
