Postcards From Perga

Book One Proposition 54, Asbury Park Boardwalk, 2015,

ink on found postcard, 4" x 6"

Apollonius of Perga did highly sophisticated mathematics with simple drawing tools while exploring ratio, proportion, and intersection—all of which I associate with visual art. I decided to use the imagery found in his work on Conics in a series of drawings called Postcards from Perga in which I am imposing Apollonius of Perga’s mathematical work onto postcards. My intention is to integrate the postcard image with the lines of the proof in such a way as to evoke emotions rarely associated with mathematical proofs, or for that matter, postcards. Mathematical imagery from the classical era is nearly timeless, and acts as a gentle foil, quietly amplifying the postcard’s ephemeral nature.
