Scans of the complete text – (Scroll down on that page and you’ll find the link to this.) This is useful because it includes Book Three – I’m quite grateful that AEMMA made this available to the public.
Scans of books one and two – I think that this was the most widely distributed set of scans for a long time, but I tend to use the previous link now, since it is complete.
Translation of Books One and Two into English – great, readable translation by Jherek Swanger, the only defect is the lack of Book Three. This is the main source I work from.
Partial translation of Book One – William Wilson‘s translation can be useful as a cross-reference, especially for those only interested in the fencing material.
Spreadsheet of all actions in the text – Reinier van Noort created a tremendously helpful resource that converts the dialog into a set of tables in a spreadsheet – very helpful for working through the actions.
NoVA-Assaulto – Steven Reich’s site for Bolognese Swordsmanship. He has many Dall’Agocchie-specific articles, as well.
Marozzo.com – Ilkka Hartikainen’s site for Bolognese Swordsmanship. He has many Dall’Agocchie-specific articles, as well, although he states that his interpretations tend to focus more on earlier Bolognese material.
Renaissance Fence – Richard Cullinan’s site for Bolognese Swordsmanship. His focus is primarily on earlier Bolognese material, but it’s still a great resource for those of us focused on Dall’Agocchie.
Order of the Seven Hearts Bolognese Page – a great resource with some useful documents and references.
Chicago Swordplay Guild Biographies – short biographies of the Bolognese masters. Dall’Agocchie is listed last.
Scherma Bolognese – a great general purpose Bolognese site – good forum, too, although not particularly active at this time.
Sword Forum International Historical European Swordsmanship subform – great place to discuss all European martial arts, including Dall’Agocchie.
