And then also the pressure of political and religious strife,
veiled in poetry during the greater part of Elizabeth's actual reign
under the forms of pastoral and allegory, again imperiously breaks
in upon the gracious but somewhat slender and artificial fashions of
England's Helicon: the DIVOM NUMEN, SEDESQUE QUIETAE which, in some
degree the Elizabethan poets offer, disappear; until filling the
central years of the seventeenth century we reach an age as barren for
inspiration of new song as the Wars of the Roses; although the great
survivors from earlier years mask this sterility;--masking also the
revolution in           manner and matter which we can see secretly
preparing in the later 'Cavalier' poets, but which was not clearly
recognised before the time of Dryden's culmination.
