Note 126 — Scene I.—The Earth, near Eden, as in Act I.
Reading edition
{258}["Time is our consciousness of the succession of ideas in our mind.... One man is stretched on the rack during twelve hours, another sleeps soundly in his bed. The difference of time perceived by these two persons is immense: one hardly will believe that half an hour has elapsed, the other could credit that centuries had flown during his agony."—Shelley's note to the lines—
" ... the thoughts that rise In time-destroying infiniteness."
Queen Mab, viii., ibid., p. 136.]
