Artefact design is not neutral, but is aimed, whether consciously or not, at different categories of users, as explained in Chapter 1. This chapter will explore design intentions as they relate to different user-groups in more detail, investigating some of the ways artefacts function to construct and maintain social categories, and also how these categories may be resisted or questioned by users. Firstly, we will examine how artefact design relates to the Roman life course, through an exploration of the motifs on finger-rings and the social categories of men, women, and children. Secondly, Roman attitudes to leftand right-handedness may be examined in relation to various items. Thirdly, we will examine some particular types of boxes and their methods of opening, artefacts in which cultural knowledge potentially impacts upon the facility with the objects may be used. In each case, we will consider how the design features may include or exclude certain users and what the implications are for a wider understanding of both Roman social practice, and the role of artefacts in enacting and reproducing social norms and behaviours. Finger-rings, among other personal artefacts, are scaled to a specific part of the body, and through this feature they provide an opportunity to examine how artefacts may have been designed for particular categories of people. Users will need rings with an appropriate diameter that is large enough to fit a particular digit, yet not so large that it risks becoming lost. Finger sizes of course vary according to age and sex, and so provide an opportunity to examine objects designed specifically for women, children, and men. We will focus here on those finger-rings displaying a central motif (usually engraved, although sometimes in relief, or occurring as a modelled form), which exist in large numbers. Most are oval in shape, and they are found in a wide range of sizes, from 9 to 27mm in inner horizontal diameter. Many are gem-set rings, and the gem iconography that they display was remarkably consistent across the Roman Empire, consisting of a range of popular themes such as the principal deities and/or their attributes, personifications, mythological scenes, animals, portraits, and objects.
