Although Bartitsu does not draw from the Italian traditions, the four hand positions clearly match. Especially for the rapier students at Academie Duello who are also Bartitsuka, I present “Boxing Interpreted as Italian Sword” without further commentary:

Prima

Capo Ferro’s First Guard

This pairs with what I call “over-pronated” punches, and what some mistakenly call “the chopper”.
prima-punch

Seconda

Capo Ferro’s Second Guard

This is the common pronated cross:
seconda-punch

Terza

Agrippa’s Third Guard

Our favoured punch, featured in most bare-knuckle boxing instructions:
terza-bare-knuckle-fighter

Quarta

Capo Ferro’s Fourth Guard

Palm-up straight punching and uppercuts:
quarta-punch
