Előadások - Ismini TRIANTI: Restoration work carried out on the Acropolis of Athen

decided to join, creating level surfaces. This tactic has rendered the precise indentification of fragments used by Balanos extremely difficult. Next year the dismantling of the two restored beams in the western hall of the Propylaia was effected. Balanos, in order to reunite the shattered fragments that made up each one of the beams, cut long channels of trapezoidal section along the upper surfaces of the beams, into which then fitted iron H-beams. Furthermore, a system of suspending the marble beams from the encased iron beams was worked out. The space between the contained structure and the walls of the channels were filled with a strong cement mix which completely covered the iron beams. The two beams of the east stoa of the central building of the Propylaia were taken apart to remove the cement and rusting iron. The same year the ionic architrave and the capital that had been restored by Balanos were dismantled. The ionic capital was immediately carried to the workshop in order to be protected from the effects of atmospheric pollution. A plaster cast of the capital was made. In the same lime the study of the standing parts of the Propylaia and the scattered architectural members has been very fruitful, allowing better knowledge of this splendid monument. About 800 fragments of the coffer slabs, which were lying on the ground and the fragments which had been used in the restoration by Balanos were studied again; this study led to numerous new identifications, which allowed the restoration of about 80 new coffer slabs, which can be used in the new restoration; new identifications were done. Unfortunately the study of the material from the central building proves that most of the missing material of its superstructure is most likely never to be found. On the contrary most of the material of the lateral wings superstructure has been identified and led to the exact reconstruction in drawing and models of the wooden roofs and ceilings. The identification of this material would allow the complete reconstruction of the superstructure of the lateral wings with only a very small amount of new marble, about 10%. The temple of Athena Nike built by the architect Calibrates between 427 and 423 B. C.

, is the smallest ofthe monuments of the Acropolis. It is amphiprostyle with four ionic columns in the east facade and four in the west side. The temple was demolisshed by the Turks before the attack of the Venetian general Morosini. Its members were found in 1835 built in the turkish bastion between the pedestal of the Nike temple and the base of the monument of Agrippa. The first restoration was planned and executed by Ross, Schaubert and Hansen. A second one was undertaken in 1935 by Balanos and accomplished by Orlandos in 1940. Yet, the iron ties were not removed, the blocks of the walls, and the cornices are not in the correct place, as is proved by the exhaustive study of the architect D. Giraud. THE WORKS OF CONSERVATION Conservation work on the Acropolis monuments focuses on the surface of the marble and has, since 1986, constituted a separate program, conducted and coordinated simultaneously with the structural restoration programs. The conservation programm executed on the monuments under the derection of the chemical engineer Evi Papaconstantinou includes: 1 Passive conservation consisting of interventions mainly of a preventive nature, such as transferring architectural sculptures from the monuments to the Museum. So far figures from the east pediment, the
