Celestine V is considered one of the most enigmatic Popes. He has been the subject of much speculation, with legends claiming he was murdered by order of his successor Boniface VIII. Assassination rumors first started in medieval times, but they were renewed in 1630 by the discovery of a nail that fitted perfectly into a square opening in his skull. During the latest Canonical Recognition, the morphology of the lesion was examined by visual inspection, showing it could not have been produced during life. The legend that the nail was driven through the Pope’s head may finally be discredited.

教皇塞莱斯廷五世头骨上的神秘洞

塞莱斯廷五世被认为是最神秘的教皇之一。他一直是许多猜测的对象，传说称他是被继任者博尼法斯八世谋杀的。暗杀传闻最早始于中世纪，但在 1630 年，由于发现了一根与他头骨的方形开口完美吻合的钉子，这些传言再次出现。在最新的Canonical Recognition中，通过目视检查病变的形态，表明它不可能是在生活中产生的。钉子被钉在教皇头上的传说可能最终会被抹黑。
