PETRIVERSE. Noun.
1) A world composed of rocks; e.g., a rock garden.
2) Words composed of rocks; i.e., verse written in stone.
[Latin petra, rock; Old English vers, from Latin versus a furrow]

Pierre Jardin coined the word 'petriverse' because no existing term adequately captured the entanglement of rocks and writing he sought when creating a site that functions as both a material essay in lithic philosophy and a revelatory garden of petric poetics.  As a world composed of rocks, a petriverse is a rock garden featuring carefully constructed rock configurations and naturally balanced stone stacks. As words composed of rocks, petriverse refers to petric texts inscribed in a landscape-oriented-page-space for perusal by a perambulatory public.  

The christening of the Petriverse pictured here is a kind of creation story, marking two births simultaneously: the emergence of the message itself from stones (petriverse, a text written in rocks), and the annunciation of the garden as a whole (The Petriverse of Pierre Jardin).  The performative nature of the message--it does what it says by doing it in words--likens it to logos (fiat lux, let there be light).  Use of alphabetic rebus (URC) foregrounds the materiality of language, and signals a regressive aesthetic, a use of signifiers to do nonlinguistic work, as in concrete poetry.  The line of stones at the bottom marks the boundary of the world being created, while the group of seven stones with one set apart stand for 6 days of creation and one of rest....  

Pierre Jardin has divided feelings about proceeding now by separating petriverse paths into world of rocks/words of rocks; the bifurcation puts asunder what had been joined together.  But as you will see, whichsoever path you choose, the one will remain imbricated with the other.
