My fine friend, there is an easy answer to it all. I could say that nothing that I composed belonged to me personally, but to the Muses, and you should have asked them for an account of what was put in and what left out. But for what I knew for myself—tending, herding, driving, milking, and the other practices and lore of shepherds—I would be rightly accountable; but the goddesses give their gifts to whom they will and for as long as they think it proper.
