The essay explores the legal history of the hand, arguing that its role in possession is not naturally given but legally constructed. Through a critical reading of Savigny, the hand is revealed as a legal artefact rather than a mere physical tool. The study examines the interplay between body and will, showing how vision and instruments (like traps) can also enable possession. It highlights how Roman, medieval, and modern legal thought redefined physical and symbolic apprehension. Ultimately, the hand emerges as both spiritualised and technologised, contributing to a broader legal organology.
