"Ettaro" is a daily diary, without elisions, whose white squares do not hide Pietro Bologna’s absences.A diary of latent images. 
During his morning walks with the dog, for several years, almost as an obsessive ritual, he has been surprised by silent appeals, invisible reflections of light that provoke a subtle reaction, that in its sacrifice—its renunciation—finds its salvation. 
Angelo Lumelli, among the few recipients of Pietro’s “good morning message”— taken with a cellphone, the photographs were despatched immediately— responded with the texts collected in this book.
