According to the museum website,
Grasso continues his exploration of space and temporality as he seeks to create what he calls a "false historical memory." In this in-between place where true and false intermingle, the all-pervading observation of the sky underlies a broader examination of seeing, watching and surveillance, at the same time as it opens up a path to possible worlds.
Please see Canadian Art for a most excellent summary of this conceptual installation.
The exhibit is a marvelous experience — the space is labyrinthine, it's dark, it's full of ambient sound, it feels like a mystery and a discovery. It feels like the videogame Myst — mysterious islands, weird technology, messages from a future past.
It's a perfect fit with the odd manuscripts lately invading my mind. Today I read about Kircher leading his blindfolded biographer into a labyrinth beneath a basilica, and as part of a science experiment. My discovery today of Uraniborg embodied the same spirit.
