Roughly worked bottom surface. Plain, square plinth (H. 0.032) under single torus (H. 0.019) under cavetto with angular frame (0.025) under three tori, the first and third squared (H. 0.042 m). Shaft has clean spiral fluting (W. 0.020 m), tapers slightly upward. Overall finely carved. Form not related to KTH277 or surviving colonettes from second-storey of peristyle.
White, somewhat fine to somewhat medium-grained, crystalline marble with faint bluish streaks. Proconnesian?
One large fragment preserves roughly two-thirds of base and part of lower shaft. Slight to moderate, sparse abrasion and chipping; thick film of encrustation.
