Column from Persepolis
Persepolitan architecture is noted for its use of wooden columns. Architects resorted to stone only when the largest cedars of Lebanon or teak trees of India did not fulfill the required sizes. Column bases and capitals were made of stone, even on wooden shafts, but the existence of wooden capitals is probable.
