The acrolith was another composite form, this time a cost-saving one with a wooden body. A xoanon was a primitive and symbolic wooden image, perhaps comparable to the Hindu lingam; many of these were retained and revered for their antiquity, even when a new statue was the main cult image. Xoana had the advantage that they were easy to carry in processions at festivals. The Trojan Palladium, famous from the myths of the Epic Cycle and supposedly ending up in Rome, was one of these.
