Report on Cultures of Ancient Science Conference Institute of Classical Studies/ Petrire Museum/ UCL, 15-17 March 2013. The Cultures of Ancient Science Conference, sponsored by BSHS, The Institute of Classical Studies, The Department of Science and Technology Studies at UCL and The Petrie Museum for Egyptology and took place from Friday 15th to Sunday 17th March 2013 at University College London. The main themes for the conference were the diversity of science in the ancient world, how we should approach the study of science in the ancient world and the possibility of making cross-cultural comparisons of ancient sciences. A further theme was how the study of ancient science had changed in the twenty years since three of the speakers (Rochberg, Lloyd, Bernall) had published seminal papers in a special edition of Isis in 1992, especially in terms of ancient science no longer being exclusively identified with ancient Greek science, along with prospects for further development. There were speakers on ancient Egypt, ancient Greece, ancient Babylonia, ancient China, ancient Rome, early Meso-America and the early Arabic/ Islamic culture. There was a most interesting reception for the conference on the Friday evening at the Petrie Museum for Egyptology. Dr. Alexandra von Lieven, an expert on ancient Egyptian science very kindly talked us through some of the exhibits relevant to the study of science in ancient Egypt. Dr. Alexandra von Lieven of The Freie Universistat Berlin gave the first paper on the Friday afternoon, speaking on ancient Egyptian science, emphasising the wealth of material now available and how the study of ancient Egyptian science is beginning to flourish. She was followed by Prof. Vivien Nutton of UCL who spoke on how the study of ancient medicine has changed in the last twenty years and is still changing. On the Saturday morning Prof. Martin Bernal of Cornell University spoke on aspects of interaction between ancient Egyptian and ancient Greek science. Dr. Andrew Gregory of UCL spoke on how he had been influenced by von Staden’s paper in the 1992 special edition of Isis, on how evidence of religious and magical belief among the Greeks had been marginalised and looked at some examples where this evidence had been excluded from modern versions of ancient texts by their editors. Prof. Geoffrey Lloyd of the University of Cambridge and Prof. Nathan Sivin of the University of Pennsylvania both discussed ancient China and to a lesser extent ancient Greece and discussed the possibilities for making cross-cultural comparisons of ancient sciences. Prof. Francesca Rochberg of Berkeley University spoke on how the history of science of ancient Mesopotamia had changed radically in attitudes and methods and the implications of this for ancient science more generally. Dr. Eleanor Robson of the University of Cambridge spoke on geographies of science and networks of knowledge among the ancient Babylonians and Assyrians. Dr. Serafina Cuomo of Birkbeck College spoke on Roman science and how it had now emerged from the long shadow thrown by the assumption that all important ancient science emanated from the Greeks. On the Sunday morning Dr. Stephanie Koerner of the University of Manchester spoke on science in pre-Columbus Andean America and discussed issues of folkknowledge and where to find knowledge in ancient cultures. Prof. Charles Burnett of the Warburg Museum closed the conference with a paper on science in the early Arabic/ Islamic civilization. There was ample time for discussion of the papers and there were many stimulating questions and comments from the audience. The conference was very well attended with around 70 people attending over the three days. The possibility of a volume of papers covering the historiography of ancient science emanating from his conference was discussed with several publishers being interested.
