ABSTRACT The doctoral thesis "Gianluigi Colalucci y su trayectoria restauradora" intends to offer a view into one of the most significant times of the italian restoration history, from the years o f the Central Intitute of Restoration - managed by Mr. Cesare Brandi - back in the 50's to the present days. This thesis, and idea of Ms. Pilar Roig, insert itself within the framework of studies and surveys carried out on important personalities among restores, so becoming subject of interest in the past few years' university activities such as the creation of the Italian and European Restorers Historic Archive, promoted by the Secco Suardo foundation. Through the study of Mr. Colalucci's personality as a restorer, it is possible to follow the evolution of techniques and scientific research in the field of restoration. The thesis is developed in six chapters; the first entitled " the training years" about the beginning at the C.I.R. and the teaching of Mr. Brandi, the second "the Sicilian time" reporting about the complex job carried out by Mr. Colalucci without much experience in Palermo, Sicily, the third " the Vatican" where it's possible to follow the work carried out inside the restoration lab in the Vatican Museums in 1960, before the restoration of Michelangelo's frescos in 1980, the fourt chapter "Rome and the Trust from 1965 to 1985" where the work of Mr. Colalucci and his commitment at the Vatican Museum is analyzed, the fifth chapter "the Sistine" is entirely dedicated to the restoring of Michelangelo's frescos inside the Sistine Chapel and the controversy witnessed by the correspondence between Mr. Colalucci and James Beck, sharp opponent to the restoration activity, the sixth chapter entitled "beyond the Sisine" where Mr. Colalucci's works after Sistine chapels and the Vatican are reported (this is as open chapter as Mr. Colalucci's activity is still on-going). As a conclusion of the long path of Mr. Colalucci's professional life it appears clear that the time of restorers of excellence is about to end, as if it's true on one hand that they have been an inpiration for young talents, on the other hand we surrender to the present cultural flattening of the society and the trend towards relying upon scientific research rather than human analytic abilities, not taking into consideration the actual abilities of the professional when assigning a restoration work, thus stopping any incentive to the hard commitment this job requires to those who love it carry it to the utmost; for the sake of the work of art itself first.
