Title |
adze (profile) |
||
Description |
English: Incomplete stone adze, tear-drop shaped in plan and section and triangular in profile, with angled sides that taper towards the butt end and widen towards the blade end. About half of the original tool survives, the sightly flanged blade end, while the longer but tapering butt end that would have been hafted is missing. The adze may have originally been about three times as long, judging from similar ethnographic parallels, in order to balance it with the wooden haft or handle. In profile the blade is plano-convex suggesting that the tool was used as an adze for carving and smoothing the wood rather than an axe for chopping.
The adze is derived from coarse gabbroic greenstone with characteristic pitted weathering. The greenstone is typical of that found in the west of Cornwall from known outcrops and contains pale felspars and dark amphibole inclusions (Roger Taylor pers comm). Similar examples have been excavated from the Neolithic settlement at Carn Brea and are illustrated in Mercer (1981) on page 155, Fig.64, Nos.S6 & S11, but the only one identified as an 'adze' is illustrated in Thomas (1962) on page 104, Fig.24, G. Similar examples can be seen on the database from Paul parish: CORN-30D0E1 and <a title="View details for CORN-FE8724" href="http://database/artefacts/record/id/486791">CORN-FE8724</a>. |
