Histories is a Roman historical chronicle by Tacitus. Written c. 100-110, it covers c. 69-96, a period which includes the Year of Four Emperors following the downfall of Nero, as well as the period between the rise of the Flavian Dynasty under Vespasian and the death of Domitian. Together, the Histories and the Annals amounted to 30 books. Saint Jerome refers to these books explicitly, and about half of them have survived. Although scholars disagree on how to assign the books to each work, traditionally, fourteen are assigned to Histories and sixteen to the Annals. Tacitus' friend Pliny the Younger referred to "your histories" when writing to Tacitus about the earlier work.
