Ash on an old man's sleeve / Is all the ash the burnt roses leave, / Dust in the air suspended / Marks the place where a story ended.
T. S. EliotWhen oxygen and sulphur dioxide are mixed in the presence of a filiament of platinum, they form sulphurous acid. This combination takes place only if the platinum is present; nevertheless the newly formed acid contains no trace of platinum, and the platinum itself is apparently unaffected: has remained inert, neutral, and unchanged. The mind of the poet is the shred of platinum.
T. S. Eliot
