Appendix I. Concerning the usage of marble tenons in Kos architecture in II century B.C.

Some (more or less fragmentary) architectural elements coming from the southern agora of Kos show features mainly related to the working of bedding and upper surfaces; some of them, in fact, show a projected cylindric tenon, made in the same block material and placed in the middle of the contact faces, while others, of the same size, are marked by a circular cavity in the same position. They are indeed white marble Doric column drums, clearly marked by Ionic influences, further proofing those mingling processes occurring in the Ionic area starting from the III century B.C. The twenty flutings appear in fact deeper than the canonical Doric ones and separated by listels approximately 1 cm wide. The surface of the shaft is not polished and there are still evident traces left by the toothed chisel. Moreover, the absence of polishing, partly due to the lack of the apergon removal, is a recurring character in the coeval Kos architecture and in some cases appears to be an intentionally pursued aesthetic choice.
