"Documenti Umani" by Federico De Roberto is a short story collection published in 1888. This work aims to document the strange psychology of human beings, following the methods of Paul Bourget's school. The thirteen stories explore hidden realities beneath surface appearances and emotions, though critics note their romantic stamp with carefully wrought prose and heightened dramatic elements. The collection represents De Roberto's developing maturity as a narrator while revealing his persistent attraction to psychological investigation and thesis-driven storytelling.
