Charles John Ffoulkes, and thus I came across a XVII century work by a French soldier, and writer Louis de Gaya, titled Traite des Armes, published during the reign of Louis XIV in 1678.
The book has some charming and quite interesting illustrations by a French engraver Nicolas Guerard and thus I am sharing them with you.
Also, I find these depictions of the period militaries interesting, albeit strangely our Polish military is curiously unhorsed and lance-less...
