    Abstract

    Anastylosis has been used as the conservation method for the late-Hellenistic Nymphaeum at the archaeological site of Sagalassos (Turkey, Prov. of BURDUR). The original fragments of the U-shaped fountain building have been excavated, and restored, with missing parts completed as a step towards reassembling all of the building fragments necessary to restore the structure. Materials and techniques used for the gluing and completing of the different stone fragments have been chosen based on the general principle of retreatability leaving aside the generally accepted use of ductile materials for reinforcement. This choice has been made despite the fact that in structural engineering ductility is often used as an additional safety domain. The technique of reinforcement and reconnecting fragments was based on the use of epoxy binder and fiberglass bars. This solution creates a brittle behavior at ultimate strength of those structural components which is less than the strength of the stone and therefore guarantees possible retreatability.

    The results of preliminary tests, the application at the site on the building and the final result of the Anastylosis are presented.
