Benedictine monk Arnold Wion printed the list in 1595 in his Lignum Vitae, saying it was newly found. No manuscript exists from Malachy's lifetime, no medieval source mentions it, and his biographer St. Bernard of Clairvaux, who recorded even minor miracles, never mentions any prophecy. Scholarly consensus since the 17th century, formalized by the Jesuit Oestreicher, is that it is a late-16th-century composition.
Supporters match mottos to popes: John Paul II as of the labor of the sun, born during a solar eclipse, Benedict XVI as glory of the olive, loosely tied to the Olivetans. The final entry, Peter the Roman, is applied by believers to whoever comes next, permanently.
The structural lesson: short, vague mottos plus motivated matching plus unlimited patience equal a perfect hit rate, the same engine that runs Nostradamus. The list is a statistical instrument for manufacturing certainty, and its final unfilled entry is the feature, keeping the prophecy permanently one pope from completion.
If the prophecy nails every pope elected before it was published and wobbles on every one after, what is it actually a prophecy of?
