Later Zeuxis and Parrhasius contributed much to the progress of painting. These artists were separated by no great distance of time, since both flourished about the period of the Peloponnesian war: for example, Xenophon [*](Memoir. III. x. 1. ) has preserved a conversation between Socrates and Parrhasius. The first-mentioned seems to have discovered the method of representing light and shade, while the latter is said to have devoted special attention to the treatment of line.
