This well-researched volume cuts through a complex era with clarity, making it engaging for both specialists and newcomers. Covering the century-long reigns of Ptolemies II–VI, it traces the rise of Ptolemaic power under Ptolemy III—whose unexpected victories brought the dynasty to its peak—and its subsequent descent into court murders, rebellion, and repeated wars with the Seleukids. From Sosibius’s ruthless manipulation of Ptolemy IV and V to the turbulent but capable reign of Ptolemy VI, Grainger delivers a sharp, compelling account of warfare, politics, and intrigue at the heart of the Hellenistic world.
