Background: Diverticular disease (DD) is a common condition, especially in Western countries. In about 80% of patients, colonic diverticula remain asymptomatic (diverticulosis), while approximately 20% of patients may develop abdominal symptoms (symptomatic uncomplicated diverticular disease, SUDD) and, eventually complications as acute diverticulitis (AD). The management of this condition has been improved, and in the last five years European countries and the USA have published guidelines and recommendations.

This contribution focuses on residues developing on spindle-whorls during spinning. Such a kind of tools is largelydiffused in archaeological contexts where spindle-whorls were used in textile activities or deposited in burials asgrave goods. Scholars recently approached the analysis of these objects through experimental archaeology to betterunderstand their wide variation in size and shape especially in relationship with the adoption of specific spinningtechniques or the quality of the fibres processed for producing different kinds of yarn.
