Illegitimate Objects is a group exhibition for which artists and poets have made work in response to the Mathematical Institute's collection of models of geometric surfaces. Made in the nineteenth century, and most likely purchased by JJ Sylvester, these models have a timeless appeal to mathematicians and artists alike.
