Factors introduced into the discussion include: a breakdown of the transmission in artistic skills due to the political and economic disruption of the Crisis of the Third Century,influence from Eastern and other pre-classical regional styles from around the Empire (a view promoted by Josef Strzygowski (1862-1941), and now mostly discounted), the emergence into high-status public art of a simpler "popular" or "Italic" style that had been used by the less wealthy throughout the reign of Greek models, an active ideological turning against what classical styles had come to represent, and a deliberate preference for seeing the world simply and exploiting the expressive possibilities that a simpler style gave.
