The cellist had fallen into one of the least forgivable of human sins, that of presumption, when he thought he could see his face, and his alone, in a portrait in which everyone could be found, a presumption which, however, if we think about it, if we choose not to remain on the surface of things, could equally be interpreted as a manifestation of its polar opposite, that is, of humility, since if it is a portrait of everyone, then I must be included in it too.
