A detailed chronological account of a military invasion of the Italian peninsula, reconstructing campaigns, diplomatic maneuvers, civic reactions, sieges, and shifting alliances. The narrative alternates with extended transcriptions of official documents, private letters, lists, and ceremonial descriptions, producing an uneven but information-rich record. At times the text gives synthesized overviews of strategic developments, while at others it switches to day-by-day entries and prolonged digressions into administrative or ceremonial detail. The mixture of documentary material and diary-like notation reflects a method of annotating events for later compilation, resulting in vivid immediacy alongside irregular structure.
