:category: draft, mantle ## From "codex" to "soundex" [[codex-calixtinus.jpeg:pic]] *The only full-page artwork in the Codex Calixtinus (Codex Compostellus), 1173, the beginning of book IV, the Chronicle of Turpin*. [^1] The "[[codex]]" form is regarded as the most significant advancement in the format of physical books. Starting in the 4th century AD, the codex format emerged as the dominant form of book, while the traditional scroll gradually fell out of favour [^2]. It replaced the form of scroll with folded collections of vellum, parchment, or papyrus sheets during the late Roman Empire, serving as the precursor to modern books. Intuitively, the name of "soundex" [^3] follows the naming schema of the "codex", and can be regarded as a cognate of the "codex". It's efficacious here for "soundex" was essentially designated for the recall of the *anamnesis* of a bygone era, and tries it best to make anything transient elements in the phenomena of sound, to be immortal, with endless repercussions. The "soundex" is hardly be said to be a experimental attempt to expand or to rectify the prevalent focuses of "field recording" to the wild field of mountaineering, but we hope "soundex" and the general MAN network solely to be near-*sui generis* and contribute to a extremely future world, which is conceivable and perceivable. Personally, the two founders lived an uneventful life at the outset, they brought up the "soundex" to complete the philosophy of themselves, to be faithful to this world, and the absolute. They gave life to their ideas, make them came to be and to grow from its first raw state to its more perfect formation in art. They strive to make unfolded ideas folded, make unformed thoughts formed, make equivocal fragmentary recordings intensively enclosed in one self-contained system-thought of acoustics approach, by applying organon and criterion. ## Design and implementation ### The design of "soundex" ### Envisioned implementation [^1]: A medieval manuscript that dedicated to Pope Calixtus II, Saint James, which is a collection of five books related to the pilgrimage to the shrine of Saint James in northern Spain.

In the third century, there were 6 out of 106 codices among pagan literature and 8 out of 17 codices among Christian works. By the fourth century, only 3 out of 14 codices were found in pagan literature, while all 36 manuscripts of Christian works were codices.
