What are the motifs in Thursday Next in Something Rotten: A Novel by Jasper Fforde?

Mythology and religion are motifs through this story. The author lampoons religious mythology as hardly ever being in line with actual reality via the St. Zvlkx character and the designs of the Goliath Corporation to become a religion. St. Zvlkx is a fraud, a time traveler, an old lecher, a drunk, and a gambler. The Goliath Corporation cares nothing for spirituality and has as its primary focus power and profits. Together they paint a grim picture of what modern religious mythology is really about: greed and control.
