Which parts of Livy’s history of Rome have survived?

Livy wrote a monumental history of Rome consisting of 142 books, but the majority of this work has been lost to time.12

The surviving portions of his history are as follows:

• Books 1–10: Covering the period from the foundation of the city through the Samnite wars.1
• Books 21–45: Covering the Second Punic War and subsequent events up to the end of the war with Perseus in 167 BCE.1

Books 11–20 and 46–142 have been lost. Beyond these surviving books, our knowledge of the later sections is limited to fragments quoted by ancient writers, a short passage regarding the death of Cicero from Book 120, and various summaries. These include a 3rd-century papyrus containing summaries of Books 37–40 and 48–55, as well as the Periochae, a 4th-century summary of the entire work.1
