All language is based on narrative. And since Dramatica maps narrative upon the structure of the Table of Story Elements, each narrative that might hold meaning in a language can be perceived as a pattern of interconnected story points.
Therefore, it is not too far a stretch to imagine that one might apply these narrative templates against previously indecipherable languages or even, perhaps, codes in order to discover the particular narrative pattern at work in the language sample.
Once the specific narrative has been determined, story points can be associated with groups of words, symbols or pictographs, so has to assign meaning to such groups, and thereby arrive at an understanding of the underlying message therein contained.’
Just an idle speculation as we watch a national geographic special on Easter Island in which their lost written language of rongorongo came up for discussion. See images of this language here, and consider the possibilities for yourself.
