A late 17th century bronze mortar, probably London
Of tapering form with flared rim, decorated to the body with two groups of three crowned Tudor roses, and with a pair of lug handles, on a flared foot, 17cm diameter x 12.5cm high
An almost identical but smaller mortar, cast six times with the crowned Tudor rose, is illustrated Michael Finlay, English Decorated Bronze Mortars and their Makers (2010), p. 75, fig. 109, and is attributed by him to an unidentified foundry, probably in London.
Another example, dated to circa 1660 - 1685 in the Colonial Williamsburg Foundation, is illustrated Rupert Gentle and Rachael Feild, Domestic Metalwork 1640 - 1820 (1998), p. 236, Fig. 3.
