The old orators were at
great pains to achieve elegance in the use of words
similar or opposite in sound. Gorgias carried the
practice to an extravagant pitch, while Isocrates, at
any rate in his early days, was much addicted to it.
Even Cicero delighted in it, but showed some restraint in the employment of a device which is not
unattractive save when carried to excess, and, further,
by the weight of his thought lent dignity to what
would otherwise have been mere trivialities. For
in itself this artifice is a flat and foolish affectation,
but when it goes hand in hand with vigour of
thought, it gives the impression of natural charm,
which the speaker has not had to go far to find.
