"... in Justinian's time, the Roman language of law, though debased—as is clearly shown by comparing the terms of any passage of Gaius' Institutes with the terms of the amending passage in Justinian's Institutes—was still equal to its purpose, and was intelligible throughout the bulk of the populations affected by the law. The intensely centralized administration and the current system of judicial procedure and appeals tended to keep the Latin tongue, if not everywhere a vulgar dialect, at all events a necessary accomplishment for all aspirants to office. At the same time the Greek language, which, in Constantinople and all the chief ports of Asia Minor, in Greece itself, in Syria, and in Alexandria, was the language of the market-place, the exchange, and, as it would seem, the polite coterie, afforded a secondary vehicle for the diffusion of Justinian's laws."
