Abstract

In 2008 the authors undertook a detailed statistical analysis of the dimensions of a large sample of loomweights from Insula VI.1, Pompeii. A major finding was that the weights of the loomweights appeared to have a bimodal distribution. Further analysis using loomweights that have come to light since the original work strengthens this observation. An analysis of loomweight volume has been undertaken with a view to predicting weight from volume for incomplete loomweights where sufficient information is retained to allow a volume calculation. Recently published experimental work allows an interpretation of the bimodality of the weights in terms of the loom set-up and the cloth being woven, and this is explored in some detail, along with further, tentative, observations on the chronology of the weights.
