The possibilities I became interested in concerned exploring what could be called proto-linguistic possibilities. Especially in the sense that these marks were, in part, the super set of marks from which many human cultures pulled the marking set developed for representing marking systems with explicitly mapped meanings.
These sets with explicitly mapped meanings include marking sets such as:
– alphabets, syllabaries, hieroglyphs, runes, and brush-characters, etc used to represent written language, that is, as the full written representation of a spoken language;
– or quasi-linguistic systems such as hobo-signs, trail signs, rail signs, or battle-signs; which, though they have explicit meanings, do not cover an entire spoken language;
-or specialized highly abbreviated notational systems such as those employed for music, movement, and modern mathematics [as opposed to, say, medieval mathematics, where the formula and relationships, with the exception of integer numbers and their basic arithmetical operations, are written out long-hand in Latin or Arabic].
Once inserted into the paintings, and frequently distorted, the marks are not intended as representations in any of these systems, but rather as human marks prior to their subsequent adoption to a specific written language, thus “proto” in the sense of “prior to” or “preliminary to” a spoken language.
