Polybius

From Wikipedia:

**Polybius** (ca. 203–120 BC, [|Greek] Πολύβιος) was a Greek historian of the [|Hellenistic Period] noted for his book called //[|The Histories]// covering in detail the period of 220–146 BC. He is also renowned for his ideas of political balance in the government, which was later used in Montesquieu's [|The Spirit of the Laws] and the drafting of the [|United States Constitution].

Polybius had become very powerful in Greece. However, he was captured and taken to Rome with 1000 other captive noble Achaeans in 186 BCE. His high status gave him a comfortable position. He stayed with __[|Aemilius Paulus]__, the conqueror of the Macedonian Wars and had ties to the Scipios (i.e. Africanus). He stayed in Rome for 17 years. Polybius traveled back and forth between Rome, Africa, and Greece before he died.
