The history of Dodnash Priory, one of numerous Augustinian priories founded in East Anglia in the twelfth and early thirteenth centuries, has hitherto been totally obscure. The two hundred original charters edited here now show that it was founded by Wimer the chaplain, sheriff of Norfolk and Suffolk and a prominent servant of Henry II, and that although always small it played a disproportionately large part in the economic and social life of south-east Suffolk for the next three centuries. The early charters include the first known references to Flatford Mill at East Bergholt; later documents relate to serious flooding at the end of the thirteenth century, and soon thereafter to the leasing of estates in order to adapt to new economic conditions. As always, the charters provide much information about local lay society as well as the canons themselves. CHRISTOPHER HARPER-BILLis Professor of English History at the University of East Anglia.
