Italianism. Repentance. Alteration or correction in a painting, drawing or other work of art on the original idea of the author, which was covered up but with the passage of time or with the current restoration techniques or inspection methods, such as x-rays or infrared reflectography , are exposed. On the Christ of Velázquez, I heard that the face did not fit his satisfaction and that, angry, the Sevillian had thrown the brush on the canvas. That's why Christ's long hair covers half the face. I do not know if this will be one of the grooming pentimenti, but in some other cases they are observable.
