Why do we examine pottery?

By Alice Beasley, Project Archaeologist

Pottery is one of the most frequently found artefacts and it is used to determine the date, status and use of a site. Today I have chosen to write about 3 ceramic vessels found within graves from a site to the south of Lincoln to illustrate how artefacts both clarify and confuse the process of determining date. The excavated part of the cemetery consisted of 23 individuals buried in a variety of directions and positions but in rough rows expected of a cemetery. Other features uncovered included pits, ditches and pottery kilns dating from the 2nd century AD and a large quarry pit with 4th century AD finds. These vessels were the only ceramic grave goods and will be used to date the burials more accurately than the stratigraphy would allow because most of the graves are discrete features – they do not cut into nor are they disturbed by other features on site.

The first vessel has been painted with a cream slip in a double zig zag over a dark brown colour coat. It is a pear-shaped beaker very similar to vessels produced in the Nene Valley in the 4th century. Interestingly this pot has no rim. “Ritual killing” of vessels is when a pot is broken or pierced in such a way that its original function is removed. Beakers are presumed to be drinking vessels so by removing the rim it’s function has been taken away. The break is very jagged and fresh suggesting that it occurred around the time of burial.

The second vessel is also a colour coated beaker, again produced in the 4th century. It is known as a slit folded beaker, about half of this vessel is missing and there are no signs of the purposeful damage seen on the first vessel as the breaks show signs of wear. Another example of this type of pot was found in Lincoln in a rubbish dump at The Park (Darling 1988, fig 39, 437).

These two vessels would lead us to believe the burials are of a 4th century date, which stratigraphically makes sense assuming that all the bodies were buried within a short period of time as a small number of them cut into earlier ditches.

The third vessel is a complete carinated bowl in a local greyware fabric.  This type of vessel is fairly common in Lincoln during the mid to late 2nd century. Affectionately named the B334 this vessel is known to have been produced in Roxby, Newton-on-Trent and Market Rasen and presumably other locations that are yet to be identified (Darling et al. 2014, 136). The beakers suggest the graves are much later than the rest of the activity on site but the bowl suggests a contemporary date. Was the pot buried soon after it had been used? Has it been kept for over 100 years to later be buried with someone? Is this an earlier grave associated with the other features on site? The pot has been used, there is some damage to the rim that has been worn smooth over time so it is possible it was an heirloom, especially as the grave cut aligns with the rest in the row which would suggest it was of a similar date to the other two graves.

The production dates of these pots will be used in conjunction with the archaeological and osteological (skeleton) information, so the final interpretation is not reliant on these three vessels alone, but understanding them it goes a long way to help us tell their story.
