The Canterbury Tales: the Man of Law's Tale Lines 442-483
By Chaucer, Geoffrey
Okay, so maybe the Sultaness isn't all bad. Sure, she's cast Custance out to sea in a rudderless boat, but she sends her with her treasure, plus some food, water, and clothing. What more could a girl ask for?
Off she goes onto the ocean.
Custance blesses herself, and in a pitiful voice prays to the Cross: "O bright and plenteous altar, holy Cross, red with the blood of the lamb that cleansed the world of sin, keep me out of the devil's clutches on the day I drown."
More prayers ensue. Custance drifts for years and days on the Grecian sea, to the strait of Morocco, as is her fate.
You might be wondering why Custance was not killed. Who saved her at the feast?
Well, the Man of Law is here to tell us: God. Obviously.
See, according to him, God desired to work a miracle through Custance, so that we might see his mighty works.
As the story goes, Christ, cure for every illness, often does things for his own purposes which are mysterious to simple humans, who are ignorant of his prudent reasons for things.
