This Frere bosteth that he knoweth helle,
And God it woot, that it is litel wonder;
Freres and feendes been but lyte asonder.

– Geoffrey Chaucer

The Canterbury Tales, The Summoner’s Prologue. The Summoner says that it is little wonder the Friar boasts how he knows hell. For there is little difference between friars and fiends, he adds.
