Abstract
This article gives new information on the so-called Letter-book of John, Viscount Mordaunt beyond that in RHS Camden Series LXIX, identifies the likely scribe, and dates the transcription to late 1660. It shows how the large format book was created to record the heroic role played by Mordaunt and his wife Elizabeth in the achievement of Restoration, and how the unfinished state of the textual project adds to our knowledge of the social and political difficulties experienced by Mordaunt, a client of Clarendon. Beyond its historiographical value for understanding the activities of the plenipotentiary, the book helps to tell the story of Mordaunt’s headlong career from his treason trial in 1658 to his impeachment in 1667, the extraordinary supportive agency of Elizabeth, including managing secret correspondence in 1659, the complexities of the Mordaunts’ friendship with John Evelyn, and their loyalty to their fallen patron Clarendon extending to exile in Montpellier in 1668.
