Abstract
The essay provides the commented edition of a hitherto unpublished prophecy and shows that it refers to an event involving the emperor Henry VII and his army; it took place around Siena at the beginning of 1313. The research also investigates the form of the prophecy. On the base of a compared analysis with similar forms, treaties and texts, which suggests some new hypotheses, the article comes to the conclusion that it should be regarded as a rhymed prose.
