Jewish War 1.14.4: Mark Antony " ...then resolved to get him made king of the Jews ... told them that it was for their advantage in the Parthian war that Herod should be king; so they all gave their votes for it. And when the senate was separated, Antony and Caesar went out, with Herod between them; while the consul and the rest of the magistrates went before them, in order to offer sacrifices [to the Roman gods], and to lay the decree in the Capitol. Antony also made a feast for Herod on the first day of his reign."
Antiquities of the Jews 14.5.4: "And when he had ordained five councils (συνέδρια), he distributed the nation into the same number of parts. So these councils governed the people; the first was at Jerusalem, the second at Gadara, the third at Amathus, the fourth at Jericho, and the fifth at Sepphoris in Galilee." Jewish Encyclopedia: Sanhedrin: "Josephus uses συνέδριον for the first time in connection with the decree of the Roman governor of Syria, Gabinius (57 BCE), who abolished the constitution and the then existing form of government of Palestine and divided the country into five provinces, at the head of each of which a sanhedrin was placed ("Ant." xiv. 5, § 4)."
