Pottery storage jar broken into about eighty sherds, with an S-shaped profile, but with no rim sherds to determine if it is everted. The shoulder and body of the vessel are incised with wider horizontal bands, running around the circumference, which border narrower oblique lines in a rough upright lattice pattern. This pattern is probably imitating the lattice decoration seen on Black Burnished ware produced in Britain during the Roman period, and particularly Black Burnished 1 (BB1) which was first produced in Dorset and other areas and was widely distributed from AD 120 to the late 4th century. The diameter of the base of the pot is about 280 mm from the curvature of the base sherds. The fabric is gabbroic, with pale felspars, dark augite and micaceous inclusions, but appears also to have non-gabbroic inclusions, such as large quartz chunks, so it is a gabbro admixture which is unusual for the Roman period (Henrietta Quinnell pers comm).
Quinnell (2004) illustrates a similar storage jar that has a gabbroic fabric and an upright lattice pattern on page 115, Fig.55, No.63, which is compared to BB1 from the late 2nd century AD.
Carlyon (1985) illustrates a gabbroic storage jar with similar decoration from Carwarthen, St Just-in-Roseland, on page 7, No.CW22, which is dated from c.AD 150-400.
Romano-British period.
Notes:
The two base sherds are photographed, in plan and in profile, and a selection of eight decorated body sherds in plan, and another selection of three larger decorated sherds, showing the exterior.
The measurements are for the largest of the two base sherds to given an idea of maximum thickness and diameter.
