But in an orator ... we demand
the acuteness of a logician,
the profundity of a philosopher,
the diction virtually of a poet,
the voice of a performer in tragic drama,
the gestures, you might almost say, of
an actor at the very top of his profession.
... Here, then, are some of the reasons
why a first-class orator is one of
the rarest things in the world.
CICERO, On The Orator
~ 55 B.C.
