respects "The Case is Altered" is not a conspicuous play, and, save
for the satirising of Antony Munday in the person of Antonio
Balladino and Gabriel Harvey as well, is perhaps the least
characteristic of the comedies of Jonson.

"Every Man in His Humour," probably first acted late in the summer
of 1598 and at the Curtain, is commonly regarded as an epoch-making
play; and this view is not unjustified. As to plot, it tells
little more than how an intercepted letter enabled a father to
follow his supposedly studious son to London, and there observe his
life with the gallants of the time. The real quality of this
comedy is in its personages and in the theory upon which they are
conceived. Ben Jonson had theories about poetry and the drama, and
he was neither chary in talking of them nor in experimenting with
them in his plays. This makes Jonson, like Dryden in his time, and
Wordsworth much later, an author to reckon with; particularly when
we remember that many of Jonson's notions came for a time
definitely to prevail and to modify the whole trend of English
poetry. First of all Jonson was a classicist, that is, he believed
in restraint and precedent in art in opposition to the prevalent
ungoverned and irresponsible Renaissance spirit. Jonson believed
that there was a professional way of doing things which might be
reached by a study of the best examples, and he found these
examples for the most part among the ancients. To confine our
attention to the drama, Jonson objected to the amateurishness and
haphazard nature of many contemporary plays, and set himself to do
something different; and the first and most striking thing that he
evolved was his conception and practice of the comedy of humours.

As Jonson has been much misrepresented in this matter, let us quote
