 It was during this period, at different times and places in the Greek world, that the use of dressed and polished stone replaced the wood in these early temples, but the forms and shapes of the old wooden styles were retained, just as if the wooden structures had turned to stone, thus the designation "petrification" or sometimes "petrified carpentry" for this process.This careful preservation of the primitive wooden appearance in the stone fabric of the newer buildings was scrupulously observed and this suggests that it may have been dictated by religion rather than aesthetics, although the exact reasons are now lost in the mists of antiquity.Not everyone within the great reach of Mediterranean civilization made this transition.
