Note 20 — Chapter I · THE EARLIEST CONSTITUTION OF ROME

The jus commercii has been read into the relations of Rome with Carthage as depicted in Polybius’ second treaty [Polyb. iii. 24, 12 ἐν Σικελίᾳ, ἧς Καρχηδόνιοι ἐπάρχουσι, καὶ ἐν Καρχηδόνι πάντα καὶ ποιείτω καὶ πωλείτω (the Roman) ὅσα καὶ τῷ πολίτῃ (the Carthaginian) ἔξεστιν]. But jurisdiction here may have been the work of some international court, and the jus commercii, without the jus exulandi, would hardly have made a foreign immigrant a citizen of Rome.
