William Langland,
The Vision and Creed of Piers Ploughman…
“ The continuator of William de Nangis, who gives a detailed account of the effects of the great pestilence on the Continent, mentions the hasty marriages which followed it, but he gives quite a different account of their fruitfulness. "Cessante autem dicta epidimia, pestilentia, et mortalitate, nupserunt viri qui remanserunt et mulieres ad invicem, conceperunt uxores residuæ per mundum ultra modum, nulla sterilis efficiebatur, sed prægnantes hinc inde videbantur, et plures geminos pariebant, et aliquæ tres infantes insimul vivos emittebant." ”
