Methodology
Little is known of the methodology by which the Victorian and Edwardian excavators achieved their goal.
Regular reports were published in Archaeologia, accompanied by plans of the blocks of the town (insulae)
and, depending on their complexity, individual buildings of note within them. There is also a limited
photographic archive.
The area within the walls was excavated block by block, since the pattern of the street grid had been largely established from the mid-eighteenth century as streets could be traced in the ripening crop. Since nothing of the town within the walls is visible above ground, it is assumed that trenching was employed as a method of identifying the locations of buildings within each insula, the plans of which were then revealed by opening up larger areas around them. It is believed that the outlying pits, wells and hearths recorded on the Victorian plans were also located by this process of trenching.
Finds
Comments on finds were of secondary importance and only individual objects of intrinsic importance were
discussed. Nevertheless attention was paid to several categories of what we would now describe as 'bulk
finds'. The excavation of wells drew attention to the preservation of waterlogged material and so seeds,
plant remains and insects were recorded. Regular specific identifications of coins were also made in the
reports. Pottery was the first category of material to receive systematic study at the close of the
excavations, and was published by May 1916. No finds curation policy is detectable however until
Joseph Stevens' acceptance of an offer from the Duke of Wellington to house the growing collection in
Reading Museum in 1891.
Insula IX
Insula IX was first excavated in 1893-4 and was therefore one of the earliest to be systematically investigated. The most effective method of exploring a rectangular area, such as a city block, where it is expected that buildings will share the same orientation as the insula, is by diagonal trenching. A number of trenches have been identified within our area of excavation of insula IX and it is now possible to suggest a sequence of events. There are 4 main phases: 1) initial exploration 2) exploration from east-west road at the north of the insula southwards 3) exploration of buildings 4) further trenching.
Phase 1 |
[Plan] |
We can trace only one trench (1060) which cut its way right across our excavated
area, and on this basis it is likely to be one of the earliest. This trench will have drawn attention to both
House 1 and Block 1 (our Building 1). A second trench (1574) originates from close to the south-west corner
of our excavation area and may have been started at the same time as the first, but it does not extend far
beyond the point of intersection with the first, where it meets a third trench (1070), parallel with, and
close to, the first. Like the second, this too does not extend right across the site. A fourth 'diagonal'
trench (1776) may belong to this phase. It is broadly parallel with trenches 1060 and 1070, and may have
started from the northern side of the insula, once trench 1060 had found the street line. It only cuts
across the outermost wall of House 1.

Phase 4 |
[Plan] |
This phase explores the remaining 'blank' areas, using each of the buildings
already discovered as the source of the trenching. Thus this phase comprises trenches dug either from the
buildings outwards, usually extending the lines of walls already found, or at close to right angles to
one of the sides. A further three or four trenches extend at right angles to the street south towards
House 1 whose wall lines they respect. Their orientation presupposes that the line of the street had
been established. The group of three 'diagonal' trenches in the south-west corner (1011, 1070, 1014)
have spaces between them of approximately 1m. This is similar to the interval between trenches 1060 and
1070 and two pairs of trenches at right angles to the east-west street at the north of the excavated
area (1317, 1331 and 1036, 1032). Of the three trenches on an east-west orientation, two in the north-east
of our area are difficult to explain: one is close to the street (1893), while the second is a relatively
shallow cut (1259), only c.1m to the south. While these were interpreted as Victorian when they were
excavated (one has produced a sherd of 19th century pottery), their character and orientation are
anomalous, raising the possibility of their having originated as Roman construction or robber trenches,
perhaps re-excavated in 1893.
Such trenches, sited to explore the 'blank' areas, were also sufficiently sensitive to identify the softer
fills of wells and substantial pits, as well as locating isolated structures such as hearths.
