Time Out says
The best public art is often designed as a direct response to the site where it’s installed, which is certainly true of this work. The Dutch-born Australian artist Petrus Spronk created his bluestone masterpiece in 1992, installed out the front of the State Library of Victoria. It represents a corner of the library emerging from the pavement like an archaeological discovery. It’s also a favourite among skaters thanks to its long, smooth edge (which has been worn down a bit over the years and is usually speckled with wax).
