I want to know the answer to the following question:
Who was Gallus disgraced by?
All the background I'm provided with is that "Ancient scholars, such as Servius, conjectured that the Aristaeus episode replaced, at the emperor's request, a long section in praise of Virgil's friend, the poet Gallus, who was disgraced by Augustus, and who committed suicide in 26 BC.". Is that enough to answer the question?
