Mortuary monuments represent conscious behaviour; they are deliberately placed to be seen and interpreted. Historic mortuary monuments therefore offer a unique dataset for analysing past social identities. This thesis examines the variation observed in one particular monument style found in Brisbane's historic cemeteries, the shrouded urn. I have identified 16 different types of shrouded urns in Brisbane and the spatial distribution and styles of these types are analysed in order to identity the social causes behind this variation, specifically in relation to the monumental masons who erected them, the consumers who purchased them and particularly the individuals for whom they were erected. In order to determine if a correlation exists between these individuals and variation in the shrouded urns, the association of different types with Brisbane's monumental masons are analysed, as are social factors relating to the deceased such as age, sex, class and status, ethnicity and religion. Consumer choices relating to shrouded urn type, as well as to monument position, size and construction material are also analysed. Monumental masons are not found to have had a large impact on the variation in Brisbane's shrouded urns; rather shrouded urn variation is attributable to the identities and attitudes both of the individuals for whom they were erected, and those who sought to memorialise them by purchasing a monument.
