Institutio Oratoria

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.

For Zeuxis emphasised the limbs of the human body, [*](I.e. by giving them roundness and solidity by his treatment of light and shade. ) thinking thereby to add dignity and grandeur to his style: it is generally supposed that in this he followed the example of Homer, who likes to represent even his female characters as being of heroic mould. Parrhasius, on the other hand, was so fine a draughtsman that he has been styled the law-giver of his art, on the ground that all other artists take his representations of gods and heroes as models, as though no other course were possible.
