For as the Romans had in the Lent lived soberly and in continence, and after at Easter had received their Saviour. After, they disordered them in eating, in drinking, in plays and in lechery. And therefore our Lord was moved against them, and sent to them a great pestilence, which was called the botche of impedimy. And that was cruel and sudden, and caused people to die in going by the way, in playing, in being at table, and in speaking one with another suddenly they died. In this manner sometime sneezing they died, so that when any person was heard sneezing anon they that were by said to him: God help you, or Christ help: and yet endureth the custom. And also when he sneezeth or gapeth, he maketh tofore his face the sign of the Cross, and blesseth him; and yet endureth this custom.
The Minor Rogation Days are of French origin, coming about in the 5th c., when St. Mamertus, Bishop of Vienne, Dauphiné instituted them after a series of natural calamities. According to the Golden Legend:
For then, at Vienne, were great earthquakes of which fell down many churches and many houses, and there was heard great sounds and great clamours by night. And then happed a terrible thing on Easter-day, for fire descended from heaven that burnt the king’s palace. Yet happed more marvellous thing; for like as the fiends had entered into the hogs, right so by the sufferance of God for the sins of the people, the fiends entered into wolves and other wild beasts, which every one doubted, and they went not only by the ways ne by the fields, but also by the cities ran openly, and devoured the children and old men and women. And when the Bishop saw that every day happed such sorrowful adventures, he commanded and ordained that the people should fast three days; and he instituted the Litanies, and then the tribulation ceased.
