First edition. The volume reflects the intellectual and political concerns of Northern Europe in the early modern period, when the composite monarchy of Denmark–Norway exercised authority not only over the Danish and Norwegian kingdoms but also over Iceland, the Faroe Islands, and other North Atlantic possessions, while maintaining complex feudal and constitutional ties with the duchies of Schleswig and Holstein. In particular, Schleswig (a Danish feud) and Holstein (a feud of the Holy Roman Empire) formed a politically entangled frontier zone, frequently discussed in legal and diplomatic literature. A collection of “various treatises” on these territories would typically address questions of sovereignty, dynastic rights, administrative organization, and territorial boundaries, often drawing on contemporary treaties, historical precedents, and antiquarian scholarship. Moreover, the date 1629 situates it in a period marked by the early phases of the Thirty Years' War, when the constitutional status of northern German territories and the Danish crown's involvement in imperial affairs were matters of acute relevance. In bibliographical terms, the book is relatively rare today and of interest primarily to historians of early modern Scandinavia and the German–Danish borderlands, as well as to scholars of historical geography and legal history. Its value lies less in originality—since it is a compilation—than in the way it assembles and transmits contemporary knowledge about a politically complex region at a formative moment in European history. The structure of the work is organized in eight treaties and a final Errata Corrige: De situ Daniae, Chorografia Daniae, Historia Gentis Danorum, Historia Regum Daniae, Daniae Descriptio, Daniae Regni Politicus Status, Ionas ab Elvervelt de Holsatia, Respublica Islandica.
