This calendar of documents in the High Court of Admiralty archives makes available a wide body of material, much of which was previously inaccessible to students of Irish history. The material covers a broad range of subjects including trade, shipping, fishing, piracy and privateering. It also sheds light on the commercial interest of Irish merchants, and on the activities of Dutch and English merchants in Ireland during the mid-seventeenth century. As such it will be a valuable resource for students of maritime history and those with interests in related economic, social and colonial themes. This volume continues on from that of John Appleby, A calendar of material relating to Ireland from the High Court of Admiralty Examinations, 1536–1641, published by the Irish Manuscripts Commission in 1992.
