Forensis reclaims the Latin relation between forensics and the forum in order to reconstruct investigation as a political and aesthetic practice. Its central proposition is that evidence does not speak automatically: objects, ruins, images, territories and environmental traces must be translated, animated and presented before heterogeneous publics. The field and the forum are therefore co-constitutive. The field is not a neutral grid but an elastic territory shaped by conflict; the forum is not merely a courtroom but a shifting assembly linking contested objects, interpreters and publics. The volume’s conceptual operation is to expand forensic practice across bodies, buildings, landscapes, digital media, law and climate while maintaining attention to chains of custody, representational violence and institutional power. Its method combines material investigation with critical reflection on the technologies and authorities that make truth publicly credible. Forensis bridges architecture, jurisprudence, media studies, human rights and political theory by demonstrating that spatial intelligence can function as evidentiary practice and that public truth is always constructed through a relation among matter, mediation and assembly.
