The sponsored monument of Thrasyllus (320/19 BC) is formed on the facade of a large cave above the Dionysian Theater and has the form of a two-door pillar. The monument was destroyed during the siege of the Acropolis by the Turks in 1827 and part of the destroyed material of the diirpagi was used in the restoration of the church of Soteira of Nicodemus. The restoration project, which began in 2011 and continued with interruptions, involved the restoration of the monument up to the height of the cornice on its eastern side and the portico, on the west, with the incorporation of most of the surviving ancient material. A new frieze stone with four emblematic wreaths was constructed with the kind sponsorship of the Ioannis F. Kostopoulos Foundation. The western member of the epistle was permanently placed on the monument, after the engraving of the missing part of the sponsoring inscription. In addition, salvage maintenance, fixing and restoration work was carried out on the two inner walls of Panagia Spiliotissa, inside the cave. The missing part of the arch in the north wall of the church was filled in to restore the structural continuity of the wall to the west. Finally, the entire pictorial decoration of the monument was preserved. The restoration project of the sponsored monument and restoration of Panagia Spiliotissa was completed at the beginning of 2017, when all the construction site equipment was removed. Thrasylleio, a telephanes monument now provides a clear understanding of a large sponsored monument of the 4th c. B.C.
