English: A complete circular biconical cast lead-alloy weight, probaby a spindle whorl dating from the Roman period judging by the form and grey patina, i.e. AD72-410. The lead weight is biconical in cross-section with a rounded base and top. It is decorated with a simple pattern of a rough chevrons. The weight is 28mm in diameter and weighs 23.5g.

Lead weights like these are common finds, but only rarely from excavated contexts which is why date and origin are difficult to pinpoint. Decorated lead-alloy weights are very rare finds in excavations, but are often found by metal detectorists. They are usually biconical or cylindrical in shape and are decorated on both faces with raised dots and radiating lines or zig-zag ribs. They have been found in ploughsoil over the site of Roman buildings, and in an excavated context dating from the 13th to the 15th century at an Austin Friary (Geake 2001). It is thus very difficult to date the decorated lead weights, and it seems that they could have been in use at any time between the Roman and Late Medieval periods. Helen Geake writes: "Dating of lead whorls is difficult. The drop spindle with which they were used continued in use until the end of the medieval period in London and Winchester (Egan 1998, "The Medieval Household: Daily Living c1150 - c1450").

Undecorated spindle whorls can date from the Roman, Early Medieval or Medieval periods. It has been pointed out that the weight of a spindle whorl is suggestive of the thickness of yarn produced, with lighter spindle whorls (3 - 5 grams) being used for spinning cotton and the heavier ones (30 - 35 grams) for spinning wool (Margeson 1993, 184). According to this, this lead whorl was probably used for spinning wool.
