What did Marcus Aurelius say about death and mortality?

In Meditations, Book 4, section 48, Marcus Aurelius builds a list meant to dissolve any illusion that greatness postpones death: "Hippocrates cured many illnesses — and then fell ill and died. The Chaldaeans predicted the deaths of many others; in due course their own hour arrived. Alexander, Pompey, Caesar — who utterly destroyed so many cities, cut down so many thousand foot and horse in battle — they too departed this life." He continues with Heraclitus, who predicted the world would end in fire but was instead "carried off" by ordinary disease, and Democritus and Socrates, killed respectively by "ordinary vermin" and by other human beings. The passage closes with a maritime image: "You boarded, you set sail, you've made the passage. Time to disembark." This is memento mori — "remember you must die" — not as morbid fixation but as a corrective. Marcus's point in cataloguing physicians who couldn't cure themselves, prophets who couldn't foresee their own end, and conquerors whose vast power bought them no extra time, is that mortality is not a special misfortune reserved for the unlucky or the ordinary; it is the one condition every human life shares regardless of achievement, wisdom, or violence inflicted on others. Writing privately as a working journal rather than for an audience, Marcus returns to this theme throughout Meditations not to induce despair but to strip away the illusion that status or accomplishment changes the terms of the deal — a reminder meant to sharpen how one uses the time actually available, since the boarding and voyage are, on this account, already well underway.
