The story, like others of the kind with a mixture of legend in them, is more symbolical than real. The wise men of Annan may have been in error in tracing the plague of their village to a single corpse, but they were probably on the right lines of causation. It is curious to observe in another chronicler of the same period, Ralph of Coggeshall in Essex, and in a part of his chronicle which relates to the last years of Richard I., and first years of John, a comment upon the action of Pope Innocent III. (about 1200 A.D.) in interdicting all Christian rites save baptism by the clergy in France: “O how horrible ... to refuse the Christian rite of burial to the bodies of the dead, so that they infected the air by their foetor and struck horror into the souls of the living by their ghastly looks[23].” The same pope’s interdict of decent burial and of other clerical rites extended to England in 1208, the famous Interdict of the reign of John. It was the papal method of checkmating the kingdoms of this world; that it was subversive of traditional decency and immemorial sanitary precaution was a small matter beside the assertion of the authority of Peter. Rightly or wrongly, taught by experience or misled by fancy, the medieval world firmly believed that the formal and elaborate disposal of the dead had a sanitary aspect as well as a pious. The infection of the air, of which we shall hear much more in connexion with the plague, was a current notion in England for several centuries before the Black Death. Especially does the dread of it find expression where corpses were unburied after a battle, massacre, or calamity of nature. The exertions made in these circumstances to bury the dead, even when all pious and domestic feeling was hardened to the barest thought of self-preservation, are explained in set terms as instigated by the fear of breeding a pestilence. The instinct is as wide as human nature, and there is clear evidence in our own early writers that its sanitary meaning was recognised. One such instance may be quoted from the St Albans annalist of the time of John and first years of Henry III.[24] In the year 1234, an unusually savage raid was made by the Welsh as far as Shrewsbury; they laid waste the country by fire and sword; wayfarers were horrified at the sight of naked and unburied corpses without number by the road sides, preyed on by ravenous beasts and birds; the foetor of so much corruption infected the air on all sides, so that even the dead slew the living. The chronicler’s language, “quod etiam homines sanos mortui peremerunt,” is marked by the perspicacity or correctness which distinguishes him. When the bubo-plague came to be domesticated in English soil more than a century later, the disposal of the dead became a sanitary question of obvious importance. But even in the centuries before the Black Death, and most of all in the times when the traditional practices of decent burial were interdicted by Popes or turned
