The Composite Fort is an artificial construct created using the percentages of the artefact functional groups from the individual Roman military installations presented on this website. The artefacts included in the excavation report(s) from each installation (at this point, mostly forts) were assigned to functional groups by sector of the fort, then the percentages for each functional group (of the total artefact assemblage from the military site) from each sector were combined and averaged, resulting in a percentage mean for each functional group. These means were used to construct the composite fort. You can examine the functional groups here, and the sectors here.
The composite fort is presented in three main aspects which correspond to the pages in this section of the website. The first aspect gives tables containing the percentage means for functional group from each sector (each sector's total artefacts are used to compute these percentage means). The second aspect presents diagrams showing patterns in each functional group spread across the fort and its sectors which were published in Roman Soldiers and the Roman Army. Eventually these diagrams will be graphed on demand and will use up to date percentages from the study database, instead of those used in the book. The final area shows each functional group and its subgroups as percentage means of the 'mother' functional group, and is currently being created.
When selecting a period to view, remember that 'AP' refers to all the periods of the fort considered together. This applies to both the composite fort tables and diagrams and the individual site percentages tables.
