Read it through once
To attempt to demonstrate the maturity of language and style of Virgil is, for the present occasion, a superfluous task: many of you could perform it better than I, and I think that we should all be in accord. But it is worth repeating that Virgil's style would not have been possible without a literature behind him, and without his having a very intimate knowledge of this literature: so that he was, in a sense, re-writing Latin poetry—as when he borrows a phrase or a device from a predecessor and improves upon it. He was a learned author, all of whose learning was relevant to his task; and he had, for his use, just enough literature behind him and not too much. As for maturity of style, I do not think that any poet has ever developed a greater command of the complex structure, both of sense and sound, without losing the resource of direct, brief and startling simplicity when the occasion required it.
