280 THE DECLINE AND FALL [Chap, xl Roman empire, the natives of Italy, of Africa, and of Britain, conversed in the groves of the academy with their fellow-students of the East. The studies of philosophy and eloquence are con- genial to a popular state, which encourages the freedom of in- quiry and submits only to the force of persuasion. In the republics of Greece and Rome, the art of speaking was the powerful engine of patriotism or ambition ; and the schools of rhetoric poured forth a colony of statesmen and legislators. When the liberty of public debate was suppressed, the orator, in the honourable profession of an advocate, might plead the cause of innocence and justice ; he might abuse his talents in the more profitable trade of panegyric ; and the same precepts continued to dictate the fanciful declamations of the sophist and the chaster beauties of historical composition.

The light of science could not indeed be confined within the walls of Athens. Her incomparable writers address themselves to the human race; the living masters emigrated to Italy and Asia ; Berytus, in later times, was devoted to the study of the law; astronomy and physic were cultivated in the museum of Alexandria; but the Attic schools of rhetoric and philosophy maintained their superior reputation from the Pelo- ponnesian war to the reign of Justinian. Athens, though situ- ate in a barren soil, possessed a pure air, a free navigation, and the monuments of ancient art. That sacred retirement was seldom disturbed by the business of trade or government ; and the last of the Athenians were distinguished by their lively wit, the purity of their taste and language, their social manners, and some traces, at least in discourse, of the magnanimity of their fathers. In the suburbs of the cit}', the academy of the Platonists, the lyceum of the Peripatetics, the portico of the
