In approaching these four plays we must prepare ourselves to judge them relatively to the other work of the very dull period of English literature at which they were written. To make this claim for them is to admit that they are imperfect, important historically rather than absolutely for their own worth; but the admission is one which no sane critic can avoid, and it is here made with alacrity. What it gains for Heywood is the recognition that two strongly marked features of these plays, one of which is now likely to repel, and the other to weary, most modern readers, in his own day helped to make them amusing. The repellent feature is, of course, that humour of filth which, quite as much as his sexual indecencies, makes some passages both in the _Four PP._ and _The Play of the Wether_ disgusting even to readers not consciously squeamish. The epithet 'beastly' which Pope applied to Skelton is certainly on this score no less appropriate to Heywood, but it needs no wide acquaintance with the popular literature of his day to learn that this wretched stuff was found amusing for its own sake. To suppress this fact, either by expurgating or by deliberately choosing a less typical play for the sake of its accidental decency, would be to falsify evidence, and any such falsification would be grossly unjust to Heywood's successors. It is only by realizing how low was the conception of humour in the sixteenth century that we can explain the existence in the plays of Shakespeare himself of passages which would otherwise be wholly amazing.
