The excavation at Buckley’s Field uncovered a range of archaeological deposits, primarily of Romano-British date, which have been subdivided into sixteen ‘Phases’. Each phase describes a broad chronological period of particualr activitis on the site; these can be summarised as follows:
|2||Pre-Roman buried soil|
|3||Pre- Roman features|
|4||Mid-late 1st century buried land surface and cut features|
|5||Late 1st century cultivation deposits and surfaces (Trench 1)|
|6||Late 1st – early 2nd century road construction (Trench 1)|
|7||Early-mid-2nd century structures and pits|
|8||Mid-late 2nd century reorganisation of building plot|
|9||Midden deposit (Trench 12)|
|10||Late 2nd – 3rd century cut features (Trench 1)|
|11||Early 3rd century burnt layer (Trench 1)|
|12||Cleaning layers (All Trenches)|
|14||1960’s John Bestwick Trench (Buckley’s Field)|
|16||Redeposited clay and topsoil (Trench 9)|

NOTE: In each phase, the deposits are referred to by their deposit (or ‘context’) numbers. Each number relates to a single event, such as the filling of a pit or the laying of a surface (a positive feature), or the action of digging a pit or ditch (known as a negative feature, or ‘cut’). Positive features are represented in the text by numbers in rounded brackets (e.g. (101), (1258) etc), negative features are shown in square brackets (e.g. ,  etc).
The numbers are taken from a register on site in sequence so that every event has a unique number to identify it. The numbers are therefore simply an identifier- they do not have any special significance. As an example, we can imagine how a rubbish pit might be formed; a pit is first excavated to make a hole; this is context . Kitchen waste is then thrown into the base of the pit containing food waste, bits of broken pottery and so on; this is context (2). More rubbish could be thrown into the pit over time, maybe from different sources such as bedding straw from a stable, ash or charcoal from a fire, and these would each be given a new number. By recording each deposit with a unique number, we can separate the artefacts out and record precisely where they came from which allows us not only to date the deposits, but to comment on such factors such as diet, land use, industry, animal husbandry etc.
On the Community Dig site, all context numbers begin with the trench number, so the deposits in Trench 1 start at 100, Trench 2 starts at 200, and so on. Deposits in Trench 12 start from 1200.
In some instances, single deposits have been given more than one number, primarily where the same deposit has been excavated more than once in different locations. These deposits are shown with an ‘=’ sign and can be considered as a single entity.
