Tempi of Change: When Soloists don't play Together. Arrhythmia in 'Continuous' Change

This contribution is centered on the question of tempi of change and the possibility of defining ternary scales of changes in a long archaeological sequence, which could match F. Braudel's interpretative framework. Although I had recently considered a ternary scale of change to be a satisfactory framework even for a single category of artifacts, further analyses for this volume, on a longer time scale, revealed it as an intellectual construct that entirely depends on the choice of criteria. In addition, observed arrhythmia in change between two sets of data from the Franchthi Cave (Greece), chipped stone assemblages and ornaments, demonstrate the difficulty of defining global phases of change within a continuous sequence. In turn, this raises the fundamental problem of the choice of proxies used to define the prehistoric cultural entities whose transformations we seek to understand.
