求翻译：Lawyer, During the Roman Republic andthe early Roman Empire, jurisconsults and advocates were unregulated, since theformer were amateurs and the latter were technically illegal. Any citizen couldcall himself an advocate or a legal expert, though whether people believed himwould depend upon his personal reputation. This changed once Claudius legalizedthe legal profession. By the start of the Byzantine Empire, the legalprofession had become well-established, heavily regulated, and highlystratified. The centralization and bureaucratization of the profession wasapparently gradual at first, but accelerated during the reign of EmperorHadrian. At the same time, the jurisconsults went into decline during theimperial period.是什么意思？
