In November 2012 an international workshop, 'Art in the Round': New Approaches to Ancient Coin Iconography, was held at the Eberhard-Karls-Universität Tübingen. At the end of 2014, the proceedings of that workshop were published: Elkins, N.T. and S. Krmnicek (eds.), 'Art in the Round': New Approaches to Ancient Coin Iconography. Tübinger Archäologische Forschungen 16. (Rahden: Verlag Marie Leidorf, 2014). Most participants were able to publish in the proceedings. Contributions explore different methods and approaches to ancient coin iconography and come from emerging and established scholars alike (Table of Contents here).
Permission was granted by the publisher to place the book's introduction online, which is available here and provides some description of the essays that follow. A kind summary of the book's contents was recently provided also by Dr. Ursula Kampmann of Coins Weekly.
