From the 90 or so articles he has published in the last two decades Professor Lloyd has chosen fifteen of the most important and influential to be reprinted in this collection. They tackle a wide range of problems in ancient Greek and Chinese thought, focussing especially on science but including also medicine, mathematics, philosophy and mythology. Three common themes the ancients' own concern with disciplinary boundaries, their engagement in polemics, and the heterogeneity of different traditions - cultivating different styles of reasoning with different results - in ancient science. Alongside papers that deal with technical issues in the interpretation of our sources, others raise strategic questions to do with the institutional framework of ancient science, the role of literacy in its development, and the underlying ontological and epistemological presuppositions of different groups of ancient investigators. The collection closes with a study in which Lloyd sets out how he sees the further comparative study of ancient science developing. Two of the articles appear here for the first time in English. The others are reprinted in their original form. Supplementary bibliographies are added referring to the most recent scholarship on the issues discussed.
