Richard Serra

"The torqued ellipses, spirals, spheres and toruses exist in the polarity between the downward force of gravity, their weightlessness and their upward rise in elevation which attempts to attain a condition of weightlessness. 
The sculptures are not objects separated in space but on the contrary they engender the spatial continuum of their environment. They impart from to the entire space, they shape the space through axes trajectories and passages between their solids and voids. 

I titled this installation the matter of time because it is based on the idea of multiple or layered temporalities. As one experiences each work in the context of the entirety of the installation one will become aware of the obvious diversity of durations of time.
The meaning of the installation will be activated and animated by the rhythm of the viewer's movement. Meaning occurs only through sontinuous movement, through anticitation, observation and recollection.

However, there is no prescribed view, no preferred sequence, no preferred succession of views. Each person will map the space differently. There is an unlimited range of individual experiences, but they all take place over time.
When I talk about time, i do not mean 'real' time, clock time. The perceptual or aesthetic, emotional or psychological time of the sculptural experience is quite different from 'real' time.
It is non-narrative, discontinuous, fragmented, de-centred, disorienting. "
