Ancient martial arts are dead and beyond recovery. Anyone who wishes to learn a method for using ancient weapons effectively must study an art originating within the last thousand years before looking at the scraps of literature and painting and sculpture which give us some hint to how Assyrians or Romans fought. We are extraordinarily lucky to have a series of European fencing manuals running back to circa 1300, and over the past decades these sources have attracted researchers willing to face the formidable scholarly, epistemological, and physical challenges of interpreting them. In Italian Longsword Guards: Comparing Vadi’s Guards with Fiore and Marozzo Guy Windsor makes a first attempt at one of these problems: the relationship between guards for the sword in two hands in the oldest known Italian writers who describe that weapon, namely Fiore dei Liberi (wrote circa 1404-1410), Philippo Vadi (wrote circa 1482-1485), and Achille Marozzo (first edition printed 1536). Vadi’s verse manual contains many names and phrases which resemble Fiore’s words, but also significant differences.
