This paper owes its inspiration to a remark made by Professor M. Rostovtzeff; in a note in his Social and Economic History of the Roman Empire on the widespread social unrest of the first two centuries A.D., having cited other literary authorities such as Dio Chrysostom, Aelius Aristides, etc., he writes: ‘The social problem as such, the cleavage between the poor and the rich, occupies a prominent place in the dialogues of Lucian; he was fully aware of the importance of the problem.’ No one, as far as I know, has attempted to collect and discuss the main passages in Lucian on this topic, and the latest writer on this aspect of Lucian reaches a conclusion quite opposed to Rostovtzeff and one which I believe to be wholly misleading. The aim of this paper is to collect and discuss the main references in Lucian to the social problem interpreting them in the light of Lucian's life and background, and the social and economic conditions of his age. In particular I shall stress the importance of the Cynic tradition as it bears on Lucian's attitude, but shall endeavour to show that this tradition is firmly rooted in practical politics and actual participation in social revolutionary movements and goes far beyond the repetition of mere ethical cliches generally ascribed to it.
