His treatise, first published by Henrico Waltkirch, is also regarded as one of the finest examples of baroque printing, with its 191 copperplate engravings by Jan van Haelbeck, Francesco Valeggio and possibly other artists.

The order's insignia, consisting of seven hearts arranged in a cross pattern surmounted by a phoenix bird, are visible on the left breast of Fabris' only extant portrait (see illustration).

The wording "Supreme Knight of the Order of the Seven Hearts" is coupled with the author's name in all editions of Fabris' work, indicating that it must have been a point of importance.

According to Hynitzsch, the editor of the 1676 German-Italian parallel edition of Fabris' treatise, on his deathbed, he bestowed his salle to senior student Herman, a German, who was later assassinated by a jealous colleague by the name of Heinrich.

Fabris also includes a Book II consisting on ways to defeat an opponent without stopping in guard, a unique occurrence among 17th-century Italian extant fencing treatises.

The section ends on the depiction of a swordsman against a half-pikeman, and with the assurance that "if you have understood the theory, you will figure out how to proceed even against the man armed with the polearm."

In his celebrated 1622 L'Academie De L'Espee, The Flemish master Girard Thibault added a chapter commenting on the excellence of Fabris' students, praising the quickness of their feints and suggesting ways to defeat them.

According to Italian fencing master and historian Luigi Barbasetti, Fabris was summoned to England to help Shakespeare choreograph the sword actions in the premier of Hamlet.

There is also an interesting, yet uncorroborated story about a Salvator Fabritz (sic) coming to Sweden in 1594 as an assassin hired by king Sigismund III Vasa, according to the Exegesis historica, written by Duke Charles and his Chancellor Nicolaus Chesnecopherus and printed in Stockholm in 1610 based on a Swedish version published in 1609.

After the meal a number of costumed Italians, including an actor and playwright by the name of Salvator Fabritz, took part in a stage-performance with drawn swords.
