Gula carum tributem exigit, sed vilissimum reddit, quia quanto sunt delicaciora cibavia, tanto fetidiora sunt stercora. Gluttony demands a heavy tribute but gives the basest returns: the more delicate the food, the more reeking the dung.

-Pope Innocent III originally Lotario de' Conti di Segni
  De Miseraria Condicionis Humanae, bk.2, ch.20.

Hypocrisy is the most difficult and nerve-racking vice that any mancanpursue; it needs anunceasing vigilance and a rare detachment of spirit.It cannot, like adulteryor gluttony, be practised at spare moments; it is a whole- time job.

-Maugham,W(illiam) Somerset
  Cakes and  Ale, ch.1.

And by his side rode loathsome Gluttony, Deforme'  d creature, on a filthy swine.

-Spenser, Edmund
