Greek and Roman Methods of Painting 
Some Comments on the Statements Made by Pliny and Vitruvius About Wall and Panel Painting

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. IE we investigate the technical processes of past ages we find that changes were very slowly introduced, and that a method of attaining the desired result, having been brought to perfection, remained unaltered from generation to generation. This conservative habit is peculiarly to be found associated with the artistic crafts, which even to-day, in spite of the discoveries of chemists and the introduction of machinery, have undergone little modification.
