This line describes the Summoner, who Chaucer also describes as pimples, "knobbes sytting on his chekes." He is so ugly that children are terrified of him. Like many characters in Canterbury Tales, the Summoner's story and his behavior match his appearance. It is course, full of earthy references and base humor, and reveals him to be a lecherous character. He is also full of insults for the Friar, making a lewd joke that associates friars with Satan, and damning him to Hell. Indeed, his entire story depicts a debased, greedy friar named John. The Summoner, overall, is not a very sympathetic character, but neither is the Friar, who provoked the Summoner's attack with an equally insulting story full of diatribes against summoners in general. By portraying the Summoner as physically ugly, however, Chaucer suggests that he is also spiritually debased.
