In The Xenotext: Book 1, Christian Bök outlined his plan to insert his poem, written as DNA, into a deathless bacterium, thereby writing a text able to outlive every apocalypse, enduring till the Sun itself expires. Now that the experiment has finally succeeded, Book 2 of The Xenotext situates that poem within the deep time of the cosmos.
Our civilization has only very limited methods for preserving its cultural heritage against a potential planetary disaster (be it thermonuclear warfare or astrophysical barrage); however, this experiment rehearses some of the techniques likely to be used in the future to preserve our archives against such annihilation.
Writing in his signature poetics, Bök speculates that, buried within the biochemistry of Life itself, there really does exist an innate beauty, if not a hidden poetry - a literal message that we might read, if we deign to seek it.
