The word "ephemera" (from the Greek) originally means day to day events, such as one reads in the daily newspapers, events that change from day to day - like the song of cicada sinking into the rocks. Yet the adjective "eternal" implies the paradox that there is something unchanging in all these changing events, that there is something eternal in all these things of time. It may be compared to a rotating circle, at each of whose temporal points a tangent may be drawn looking out of the circle to eternity.
