Title |
Roman lead cistern base in situ |
||
Description |
English: A telephone call received on the afternoon of Sunday 13 September 2020 alerted this reporter to the discovery of a large lead object on a Roman site outside Rudston, East Riding of Yorkshire, by two metal-detectorists. I agreed to attend to view the site the next day, with a view to the archaeological retrieval of the object if feasible.
A cast lead flat-based cylindrical object with an internal fringe of projecting iron nail shanks, driven from the outer side, of surviving lengths 40mm and spaced 45mm apart was identified. The object was 600mm in diameter, flat-based, with a plain square-topped rim at the top of a vertical wall 100mm high and of a uniform thickness of 10mm. A single nail-end projected so as to suggest an original length of 60mm for all of the nails, but was lost in the course of excavation. The object occupied the base of a circular pit of 750mm diameter cut 400mm into chalk subsoil. The pit had been dug at the end of an ash-filled channel 0.65m wide and alongside the tumbled rubble of a wall footing. The footing included chalk rubble and sandstone quern fragments, and part of this structure had collapsed over the leaden object after its disuse. Roman pottery and burnt animal bone was recovered from above and below it. The object has yet to be weighed, though moving it was a two-person job. It is inferred that the object was the nailed waterproof end of a cylindrical or barrel-shaped tank, cistern or pump base. The use of lead implies a connection with water supply or storage. It had been installed within or immediately adjacent to a pre-existing structure, and at one end of an ash-filled linear feature. Suggested date: Roman, 100-410 |
