Marcus Aurelius
Meditations 9.36
The rottenness of the matter which is the foundation of everything! water, dust, bones, filth: or again, marble rocks, the callosities of the earth; and gold and silver, the sediments; and garments, only bits of hair; and purple dye, blood; and everything else is of the same kind. And that which is of the nature of breath is also another thing of the same kind, changing from this to that.
Marcus Aurelius, Meditations 9.36, translated by George Long
Seeds of decay in the underlying material of everything—water, dust, bones, reek! Again, marble but nodules of earth, and gold and silver but dross, garments merely hair-tufts, and purple only blood. And so so with everything else. The soul too another like thing and liable to change from this to that.
Marcus Aurelius, Meditations 9.36, translated by C. R. Haines
