At the period when this poem was first published, England, in common with the rest of Europe, had been struck with a succession of calamities. Little more than twelve years had passed since a terrible pestilence had swept away perhaps not less than one-half of the population.[6] The lower classes, ill fed and neglected, perished by thousands, while the higher ranks--the proud and pampered nobility--escaped; "he who was ill nourished with unsubstantial food," says a contemporary writer, "fell before the slightest breath of the destroyer; to the poor, death was welcome, for life is to them more cruel than death. But death respected princes, nobles, knights, judges, gentlemen; of these few die, because their life is one of enjoyment."[7] It was the general belief that this fearful visitation had been sent by God as a punishment for the sins which had more particularly characterised the higher orders of society; yet instead of profiting by the warning, they became, during the years which followed, prouder, more cruel and oppressive, and more licentious, than before. Another pestilence came, which visited the classes that had before escaped, and at the same time a tempest such as had seldom been witnessed seemed to announce the vengeance of heaven. The streets and roads were filled with zealots who preached and prophesied of other misfortunes, to people who had scarcely recovered from the terror of those which were past. At this moment the satirist stepped forth, and laid open with unsparing knife the sins and corruptions which provoked them.

From what has been said, it will be seen that the Latin poems attributed to Walter Mapes, and the Collection of Political Songs, form an introduction to the Vision of Piers Ploughman. It seems clear that the writer was well acquainted with the former, and that he not unfrequently imitates them. The Poem on the Evil Times of Edward II. already alluded to (in the Political Songs) contains within a small compass all his chief points of accusation against the different orders of society. But a new mode of composition had been brought into fashion since the appearance of the famous "Roman de la Rose," and the author makes his attacks less directly, under an allegorical clothing. The condition of society is revealed to the writer in a dream, as in the singular poem just mentioned, and as in the still older satire, the _Apocalypsis Goliæ_; but in Piers Ploughman the allegory follows no systematic plot, it is rather a succession of pictures in which the allegorical painting sometimes disappears altogether, than a whole like the Roman de la Rose, and it is on that account less tedious to the modern reader, while the vigorous descriptions, the picturesque ideas, and numerous other beauties of different kinds, cause us to lose sight of the general defects of this class of writings.
