'Lives of Grass,' Mathilde Roussel
According to the website of artist Mathilde Roussel, these eerie sculptures (titled "Lives of Grass") are meant to represent the growth and decay of life. Though they are suspended in midair, they convey a sense of gravity — "of time, of existence, of limitation, of frailty." The use of live wheatgrass to compose the piece creates a heightened contrast.
The metal and fabric that holds the structure together is recycled, perhaps as an allusion to the fact that all living things are composed of borrowed materials.
