Only Roman material is present in
this sample. There are three examples of tegula, and where the flange survives
it is very large (78mm high). This is a
noted trend in York material, and it is larger than the average tegula in
Britain. It has been suggested that
this size of material is the product of the legions, and smaller flanges (which
do occur in York) are from civilian factories or are later in date. The pottery dates from context ZE9 are 1st
century, which supports an early date for such large flanges.
Another possibly early product is the
fragment of wall tile or half box flue from context ZE9. The fragment has diamond-shaped scoring on
the sanded side, and is smooth on the other.
The fragment also appears to be sooted, including along a broken
edge. This example also has a looped
signature on the smooth side. A wall
tile would be flat, and may have had small cut outs along the edges to facilitate
the fitting of holdfasts and associated spacer bobbins. A half box flue would have looked like a
tegula, but would have cutouts in the centre part of the flange to help the
flow of air circulate along the wall.
The flange would be quite square, and fairly high. These types of cavity wall heating tend to
be associated with earlier Roman phases.
Context ZE9 has several examples of
Roman brick, defined by the thickness of the fragment. The sizes cannot be gauged from such small
fragments. These could be used in
walls, floors and hypocausts.
There is a worked limestone block
from ZE11. It is worked on at least
three faces, and would benefit from being examined by a geologist
