Book 2 of The Xenotext situates poetry within the deep time of the cosmos, striving to create a poem that might persist upon the surface of the Earth, enduring until the death of the Sun itself. Our civilization has only very limited methods for preserving its cultural heritage against a potential planetary disaster (be it an atomic battle or a meteor impact); however, this experiment rehearses the techniques likely to be used in the future to preserve our archives against such annihilation, revealing that, buried within the biochemistry of life itself, there really does exist a poetic lesson that might teach us to protect our most insightful epiphanies from oblivion.
