The Layout and Internal Development of Celtic Fields: Structural and Relative Chronological Analyses of Three Danish Field Systems

Abstract

The layout and development of field systems may reflect significant aspects of prehistoric societies such as agricultural strategies, use rights and inheritance practices. This article presents a method for analysing the developments of field systems in their entirety, based on a hierarchical sorting of field boundaries whose intersections have been used to define relations of equivalence and subordination. The formalized relational expression of the field system is analysed using a stochastic optimization algorithm. The method was successfully applied to three Danish Celtic fields from the Late Bronze/Early Iron Age, making it possible to identify five principles behind the layout: primary boundaries (probably established at community level), major parcels (administered at a household level), structured subdivisions (presumably related to inheritance), irregular subdivisions, and small-scale expansions of the field systems. The initial degree of regularity of the field systems seems to have influenced later modifications.
