death to capslock

I was re-reading some old DTCL posts, and started wondering about prophecies. Specifically, about what a young, Dark Arts-curious wizard might know--or believe--about how they work.

Divination class, as we see, teachings more indirect predictive methods, such as reading tea leaves and cystal-gazing. Actively channeling... something... to deliver a prophecy isn't taught as far as we know, and likely can't be. Moreover, that particular method seems to be rather obscure. An official Mystery, in fact.

But there are literary depictions of prophecies. And both Shakespeare and Sophocles lived before the Statute of Secrecy, and their works might be find in wizarding libraries regardless of their authors' actual magical abilities or lack thereof. Their depictions of how prophecies usually work may have been based on fact. At least in part.

Would a geeky young wizard combing through every reference he could find to the Dark Arts read Macbeth and Oedipus the King, one wonders? As part of being thorough? And wonder if, perhaps, trying to prevent a prophecy from coming true really will not only be futile, but might even be the very means by which the prophecy will come to pass? Or at least, the attempt could make the prophecy come to pass sooner than it otherwise would have?

Hypothetically, if such a young wizard overheard part of a prophecy while trying to apply for a job, on his terrifying new master's orders--perhaps with some vague hope of using the opportunity to switch sides, but scared off by the opposition's disdain--would he at least have reason to hope that delivering said prophecy to the terrifying master would actually be a way to strike a blow? A desperate hope, for desperate circumstances? (He'd surely noticed by then how, erm, suboptimal the working conditions under Voldemort were.)

When Severus told Voldemort that a prophesied enemy could defeat him, what exactly did he think might happen should Voldemort respond by trying to kill that enemy?

Very possibly, something more than just that enemy getting AK'd.

Very possibly, the same thing Dumbledore thought might happen: Voldemort would be arrogant enough to think he could outwit a prophecy, and would destroy himself in trying to prevent it.

Then Severus and all his friends could put that nightmare behind them, without having to risk their lives and their families (like, say, the expected Baby Malfoy). Whew! Brave, but saving their necks if possible.

How unfortunate that this turned out to mean Sev's childhood best friend would die in the process! But then, he should have known better. Trying to manipulate a prophecy is liable to rebound on one, after all. Yet another reason for him to wish he had died, afterward.

If he'd just kept his mouth shut, might Harry have been born in the wee hours of the morning of August 1?
