Pillar at the Temple at Edfu
At the lower part of the capital there frequently occurs an ornament of diminishing triangles, resembling the sheath from which the stalk of a plant springs. The same ornament often occurs at the base of the shaft, and seems to a certain extent borrowed from the shape of the lower portion of the papyrus plant (here). Other capitals imitate an unopened bud or seed-pod.
