Early Italian fencing treatise by Antonio Manciolino, printed at Venice in 1531 by Nicolo d'Aristotile, detto Zoppino. Gelli stresses its importance as one of the earliest printed Italian works on arms and remarks that it treats quarrels and gentlemanly conduct as much as technical fencing.
Castle also records the Venice 1531 Manciolino witness printed by Nicolo d'Aristotile detto Zoppino.
Vigeant 1882 treats Manciolino as one of the earliest Italian fencing writers, but says the 1531 Opera nova still offers only a sketch of the bases of fencing, with woodcuts that function as ornaments rather than true illustrations of the text.
