Some say this person is the martyr Saint Peter. You must know, before Jesus ascended, he appointed him as the dean to shepherd his flock. Later, Peter, in order to fulfill the mission as the chief apostle, preached the gospel, disregarded others' dissuasion, and traveled alone to Rome during religious difficulties, ultimately being martyred by being nailed upside down on a cross by the Roman Emperor Nero.
But regardless of whether it's Prometheus or Saint Peter, the hanged man represents the need for great sacrifice and compromise for a broader goal. Meanwhile, the hanged man, with his head down and feet up, also symbolizes viewing the world from a different perspective, requiring calm contemplation, reflection on one's past, and then stepping forward.
