Seneca · On style as a mirror of character
Letters 114.15
Let us now turn to the arrangement of words. In this department, what countless varieties of fault I can show you! Some are all for abruptness and unevenness of style, purposely disarranging anything which seems to have a smooth flow of language. They would have jolts in all their transitions; they regard as strong and manly whatever makes an uneven impression on the ear. With some others it is not so much an “arrangement” of words as it is a setting to music; so wheedling and soft is their gliding style.
Seneca, Letters to Lucilius 114.15, translated by Richard Mott Gummere
