I want to know the answer to the following question:
Who was Gallus disgraced by?
All the background I'm provided with is that "At Maecenas' insistence (according to the tradition) Virgil spent the ensuing years (perhaps 37–29 BC) on the long didactic hexameter poem called the Georgics (from Greek, "On Working the Earth") which he dedicated to Maecenas.". Is that enough to answer the question?
Answer: no
