This little story, set in the city of Urbicande, totally took my by surprise. Urbicande is a city obsessed with architectural perfection, massive building, straight lines with no details, and clarity of design (think the Pyramids...) One day, while digging for a new construction, a strange cube is found, a cube so hard that it breaks the diggers (in reality, it is not really a cube, rather just the edges of an empty cube...) While the head architect ponders about the meaning of this, he notices that the cube seems to grow; this growth turns out to be exponential, and unstoppable.
And this is where the fun starts. The cube, starting small and growing, bigger and bigger, can be interpreted in any ways you want (even many interpretations are suggested at the end of the book...)
I would say the cube was an analogy with the very concept of an ideas. An idea that starts small, in this instances even discovered by accident, and then begins to grow, to eventually encompass all aspect of the life of the city. And how do the authority react to this idea/cube? When at first the cube is very small, it is with lack of interest, denial even. Then as the cube extend to the size of a few buildings, thus begins an active and aggressive attempt to destroy it, with tools first, then with weapons. Once it becomes obvious that the cube can't be destroyed, the government pivot to a vigilant monitoring of the cube, controlling its uses by the citizen rigorously. Even that, eventually, does not work. People start the ignore the rules, discretely at first, then more openly, as the repression fades... until eventually almost everybody realizes that the presence of the cube, while disturbing to the architectural perfection of the city, enriches their life, allowing them to create connections with others. So much than once the cube is gone, they attempt to rebuild it, with little success.
Whatever this analogy might turn out to be, religion, God, political or financial system... I think it can be many things, or maybe nothing, maybe just a story about how, as I said, an idea from humble beginning can grow, and grow, like an unstoppable force, to a point where it structures the entire life of a community. When the cube is gone, as I said, and the city attempts to replace it with no success (it only results in tragedy) perhaps it is also saying something about the divine nature of ideas and the corruption that human action imposes on them, in a very Platonic reading.
Who knows, but it was very interesting to me. Of course, being a French comic, there must be an rather uninspiring love story that seems to bore even the protagonist... I think involving love in that story was a great idea, bringing a little chaos in there, love, the x factor, but it is not given the philosophical considerations it should here, therefore remaining rather like a moot point.
Nonetheless, I will scramble to find more work from this series now, and I hope that they all have the same philosophical tendencies. It might be hard, this is rather obscure. Should be better known.
