In 1725, a plan of the town of King’s Lynn (Fig. 13.2) was engraved by William Rastrick, a preacher who became a minister to the town’s Presbyterian congregation.7 Although Rastrick’s plan incorporates several familiar elements, such as the lists of important institutions and illustrations of important and imposing buildings, it introduces two novel features: the common seal and civic regalia. The Lynn common seal still survives. It is a two-part matrix in high-quality copper alloy with one part showing St Margaret with a dragon at her feet with the legend SUB MARGARETA TERITUR DRACO STAT CRUCE LETA (Happy Margaret stands, the Dragon is ground under the Cross) (Fig. 13.4). The choice of saint relates to the town’s church of St Margaret, founded in 1101 by Bishop Herbert de Losinga, which was under the jurisdiction of the bishop until 1537.8 The other matrix (Fig. 13.3) shows the eagle of St John the Evangelist carrying a scroll and the words IN PRINCIPIO ERAT VERBUM (in the beginning was the word).9 The legend of this part of the matrix reads SIGILLUM COMMUNITATIS LENNIE.10 The inhabitants of King’s Lynn had a very strong relationship with the common seal. For example, the local Grammar School recorded the use of the seal in congregation ceremonies in the seventeenth century; a tradition that continued for many decades.11
