What is ironic about prince prospero name in masque of the red death?

In Edgar Allan Poe's "The Masque of the Red Death," Prince Prospero's name is ironic because "prospero" suggests prosperity and success, yet he is ultimately powerless against the deadly plague ravaging his kingdom. While he tries to isolate himself and his guests from the Red Death in his lavish abbey, his efforts are futile, highlighting the theme of the inescapability of death. Thus, his name contrasts sharply with his grim fate, emphasizing the illusion of control in the face of mortality.
