10. BRYCE: ROME AND ENGLAND 335 the old customs of the nation, which had been for the most part preserved by oral tradition, were written down, being no doubt modified in the process. 2. The days of the First and Second Punic Wars, when the growth of population and trade, the increase of the number of foreigners resident in Rome, and the conquest by Rome of territories outside Italy, began to induce the development of the Praetorship as an office for expanding and slowly remodelling the law. 3. The end of the Republic and early days of the Empire, when there was a brilliant development of juridical litera- ture, when the opinions of selected jurists received legal authority from the Emperor's commission, when the Senate was substituted for the popular assemblies as the organ of legislation, and when the administration of the provinces was resettled on a better basis — all these changes inducing a more rapid progress of legal reform. 4.

Rome was a City which grew to be the civilized world: the Urbs became Orbis Terrarum. The English were, and remain, a people inhabiting the southern part of an island, and beyond its limits they have expanded history of the law goes on to a. d. 1204, and in a sense even to a. d. 1453, in an unbroken stream, the codes issued by the later Emperors, and especially the Basilica of Leo the Philosopher, being based upon Justin- ian's redaction.
