The section of a fluted Ionic column in the center of this room stood over fifty-eight feet high in its original location at the Temple of Artemis. The delicate foliate carving on the capital is unique among extant capitals from the temple, and the torus (foliated base), with its vegetal scale-like pattern, is also exceptionally elaborate. This capital is slightly smaller than others found at the site, indicating that it does not belong to the outer colonnade. Two similar pairs of columns (marked in red on the plan shown nearby) stood in the east and west porches. The column, displayed here with most of the shaft omitted, was probably originally from one or more of those pairs. Alternatively, it may be from the cella (inner room) or from the inner back porch. Parts of the fluted shaft are restored, and the profiled base below the torus is a copy of the original.
