While making a contribution to the discussion about Lesmian's synchronism this article tries to demonstrate that 'Savagery of Posthumous Habits', the last of his known works, marks a notable expansion and evolution of the poet's imagination. This new departure is most evident in the greater complexity of his characters' psychology, quite distinct from his customary design of the afterlife, and in the infusion of carefully worked out elements of movement and light into his traditionally colourful descriptions. Further evidence comes from an analysis of the plot structure and characterization, especially the construction of character profiles, the characters' speech and ways of self-realization. Apart from the diversification of idiolects Lesmian's last work employs a whole range of theatrical techniques such as scenic presentation, stage directions, props, etc. While retracing the investigation, which functions as the frame of the action, the article examines the reasons and causal sequences of the events depicted in Lesmian's drama.
