*
3 points
Black scabby brows he had, and a thin beard./ Children were afraid when he appeared.
No quicksilver, lead ointment, tartar creams,/ No brimstone, no boracic, so it seems,
But well I know he lied in what he said;/ A curse should put a guilty man in dread,
On any young fellow in the diocese./ He knew their secrets, they did what he said.

Answer 1

The line "But well I know he lied in what he said" does not show the author's attitude towards the Summoner.
