The first volume focuses squarely on the Ottoman campaigns in Hungary and Transylvania from the mid-sixteenth century onward. It ends with a peace agreement between Selim II, Sultan of the Turks, and Maximilian II, Holy Roman Emperor. The second volume is a much wider history of the wars between the Ottoman Empire and European powers. It covers the siege of Malta, the Battle of Lepanto and the capture of Cyprus; it gives further information on the wars in Transylvania, Hungary and Dalmatia. The second volume further discusses the Ottoman campaigns against the Persians, the Georgians and the Ethiopians; and it has a lengthy account of the exploits and heroism of Philippe Emmanuel de Lorraine, the Duc de Mercceur (Mercury), who entered the service of Emperor Rudolph II and was his Lieutenant General in his wars with the Ottomans in the 1590s. The second volume is dedicated to Henry IV, King of France. It also contains a Latin panegyric on Henry IV by Pierre Mousson. Fumée's work had been translated into German in 1596 and into English in 1600 by Rooke Churche.
