This paper investigates Roman writing habits through the evidence of metal styli. An assemblage of more than 400 styli from London constitutes the basis of the analysis, which explores their similarities with examples from other sites in Britain and continental Europe during the Imperial period. The geographical and social distribution of styli suggests that certain types were employed or made in specific locations by different social actors, and that the major political and military centres of the Empire shared a common material culture of writing. The analysis also suggests that styli types of the northern European regions possibly developed from ‘military styli’ brought by soldiers and bureaucrats during the conquest.
