Chi vuol che una piaga sfoglie bene, paghi bene il medico : n’ è vero, Maestro? e chi vuol guarir lo paghi male.

Translation: He who would ease the pain of his wound, should pay his doctor well. Isn’t it so, Doctor? And he who would be cured should pay him badly. | Translation reported in Harbottle's Dictionary of quotations French and Italian (1904), p. 274.
