The results of the post-excavation analysis of the excavation records are presented as nine periods of activity (Table 3). These periods are, in some cases, further sub-divided into phases which represent distinct changes in activity or sequence during a period such as 'construction', 'use' and disuse'. The definition of these periods has been achieved through a programme of detailed stratigraphic and structural analysis, which also assimilated the results of the specialist assessments.
Dating relies principally on ceramic and CBM dates, which were used to rectify the stratigraphic diagram. A small assemblage of coins and a rich collection of dateable artefacts has been used particularly where intrusion or residuality was suspected. A high degree of intrusion, particularly of Humberware sherds, was noted by the ceramic assessment in deposits otherwise thought to be of Roman to high medieval date. The frequency and intrusion of this particular pottery type has been attributed to the production of pottery at the site, and its presence in features which, stratigraphically, could have been earlier has been subject to critical examination, particularly since it was contained in some quantity in the post-Medieval soil overburden of the site. Intrusion was particularly high in features of Anglian date. Excavation at 46-54 Fishergate also encountered levels of intrusive pottery, particularly in Anglian features, which was attributed to the 'settling of lower fills and the consequent slumping of stratigraphically later layers' (Mainman 1993, 563). In addition, the presence of an orchard at the site from the mid-16th century was manifest as root-disturbed features throughout the site, and the presence of mature fruit trees overlying archaeological features may have contributed to high levels of intrusion.
A total of eight radio-carbon dates has been selected from targeted stratified burials in order to test the different hypotheses posited for the date and layout of the cemetery. Additionally, a grave which was positioned outside the main concentration of burial, and which was cut by a feature containing 12th century pottery, has been selected in order to test the possibility that it may be Roman in date. Until the results of radiocarbon dating are returned, the cemetery is narrated alongside the high and later medieval periods, although it is acknowledged that its foundation could well be earlier.
AutoCAD drawings of the features associated with each period are available in the Phases section of the Archive page.
