Week 3: Omens

What turns an ordinary event into a sign, across cultures and centuries — and what an omen is actually doing for the person who reads one.

Omens are one of the oldest recorded technologies for managing uncertainty. Roman augurs read the flight of birds before a military campaign. Mesopotamian priests read the livers of sacrificed animals. A modern reader who would never consult an augur still touches wood, avoids walking under ladders, or feels a flicker of unease about the number of a hotel room. The specific vocabulary changes; the underlying move does not.

That move has three parts, and this week’s activity is designed to make you try all three rather than pick the “right” one, because all three are operating at once. First, an event has to be noticed — singled out from the thousands of neutral events in a day. Second, it has to be linked to an outcome, usually one that already worried you. Third, the link has to survive contact with what actually happens: a hit gets told as a story for years, a miss is quietly forgotten within the hour. None of this requires the omen to have any causal connection to the outcome at all — the entire system runs on noticing, linking and selective memory.

Omens as a political language#

Omens weren’t only private anxiety management — for most of recorded history they were public infrastructure. A Roman general who saw an unfavourable flight of birds before battle could call off the engagement without losing face, because the gods, not his nerve, had made the call. Suetonius and Plutarch both record a cluster of reported omens in the days before the assassination of Julius Caesar in 44 BCE — a soothsayer’s warning about the Ides of March, a sacrificial animal said to be found without a heart, Caesar’s wife Calpurnia dreaming of his death the night before. Whatever actually happened astronomically or biologically, the story of the omens did real political work afterward: it let Rome narrate an assassination as something the cosmos had been trying to prevent, rather than a plain conspiracy among men who wanted power. An omen reported after the fact is doing legitimacy work, not prediction.

Two skies, one move#

The same mechanism shows up wherever people have watched the sky, and it is worth comparing two traditions side by side rather than treating either as the “superstitious” one. In 1066, Halley’s Comet appeared over England weeks before the Battle of Hastings; it is stitched into the Bayeux Tapestry directly above a shaken King Harold, recorded by contemporary chroniclers as a portent of the regime change that followed. In imperial China, court astronomers kept centuries of meticulous records of comets, eclipses and planetary movements precisely because unusual sky events were read as Heaven commenting on the legitimacy of the reigning dynasty — a tradition sophisticated enough that Chinese astronomical records are still used by modern scientists reconstructing historical supernovae. Both systems are doing the identical interpretive work: an ordinary astronomical event, occurring on its own physical schedule with zero regard for human politics, gets read as commentary on human politics anyway, because someone with a stake in the outcome was watching the sky and needed it to mean something. Neither tradition is more credulous than the other; both are equally sophisticated responses to the same three-part mechanism above, aimed at the same target — legitimacy — with different vocabularies.

This doesn’t make omens meaningless as practices. A pre-exam ritual can genuinely reduce anxiety and improve performance, whatever its official justification. The question this course keeps returning to is not “does this work” but “what is it actually doing, and is that the same thing it claims to be doing.”

What this changes#

An omen is the week-1 detector plus an audience. The noticing-and-linking machinery is identical to pareidolia; what’s new this week is that the link, once made, gets told to other people, and telling it changes what it does — a private hunch becomes a shared reason to act, retreat, or crown a successor. That’s the shift this course tracks for the rest of the semester: weeks 4 through 9 keep asking the same three questions (what got noticed, what got linked, who benefits from the story), moving steadily from the most private version of the pattern (a dream, told to no one) to the most public one (an algorithm, read by everyone it targets).
