ignorance of those who practise it, and of those who, inconsiderately,
form a judgment of them, it is at present far behind all the other
arts. Their mistake appears to me to arise principally from this, that
in the cities there is no punishment connected with the practice of
medicine (and with it alone) except disgrace, and that does not hurt
those who are familiar with it. Such persons are like the figures[397]
which are introduced in tragedies, for as they have the shape, and
dress, and personal appearance of an actor, but are not actors, so also
physicians are many in title but very few in quality.
