Cassius Dio's reported silvery fall over the Forum of Augustus

Record summary

What happened The supplied summary attributes to historian Cassius Dio a report that, in AD 196, a fine silver-like precipitation fell from an otherwise clear sky over Rome's Forum of Augustus. Dio was said to have applied some of the material to bronze coins; the apparent silvery layer reportedly vanished after four days. Evidence The packet contains only a Wikipedia excerpt paraphrasing and attributing the account to Cassius Dio. It does not supply Dio's original text, a translation, manuscript information, contemporary corroboration, physical samples, the coins, or any analysis of the alleged coating. Explanations considered The supplied excerpt does not offer an identification or conventional explanation for the reported fall or the temporary coating. The label “angel hair” is the title of the secondary source page, not evidence that the material had a particular origin. What remains uncertain This packet cannot establish the precise date beyond the reported year, the composition or amount of any material, whether coins were actually coated, or why the coating reportedly disappeared. It also cannot determine whether Dio's account was literal observation, a later transmission, or an extraordinary aerial event. Primary source Angel hair — Wikipedia reported-sighting index
