The author presents the Early Helladic III pottery from Lerna in all its aspects, cataloguing, describing, and classifying over 1,400 vessels. The classification systems are based on detailed analyses of vessel shapes and ornamentation, supported by shape and pattern charts and numerous tables and illustrations. The concluding chapter compares the Lernaen pottery sequences to contemporary developments in central and southern Greece and examines the lineage of Early Helladic III pottery, which differs so profoundly from the pottery of the preceding period. Physico-chemical analyses of the ceramic material are presented in an appendix.
