Institutio Oratoria

For it was Aeschines who introduced the culture of

Athens at Rhodes, which he had chosen as his place of exile: and just as certain plants degenerate as a result of change of soil and climate, so the fine Attic flavour was marred by the admixture of foreign ingredients. Consequently certain of the orators of this school are regarded as somewhat slow and lacking in energy, though not devoid of a certain weight, and as resembling placid pools rather than the limpid springs of Athens or the turbid torrents of Asia.
