According to Tomasz Jurek, both, the coat of arms Brochwicz and its name could have been shaped already in the 12th century. According to this researcher, several Silesian coats of arms shown in miniatures in the "Lubin Codex", including the coat of arms Brochwicz, belonged to families with old certificates and Polish origin and Polish connections. According to Józef Szymański, the Brochwicz coat of arms, which can be found among those depicted in the miniatures of the "Lubin Codex", has references to forms known in Polish heraldry. Its appearance reflects heraldic situation prevailing in Silesia in the mid-fourteenth century. Consequently, strong foreign influence shaped its appearance. The first mention of the coat of arms dates back to the Teutonic Order period, and more detailed information is found in 1544. The name Brochwicz probably comes from the word "paroháč", transformed into "broháč" and then polonized to the form "Brochwicz". The origin of the coat of arms, however, does not need to be Czech. Medieval Polish and Czech languages, both Slavic, had a lot of similarities.

The coat of arms was depicted in miniatures depicting Silesian knights participating in the Battle of Legnica against the invasion of the Mongols. It depicts black deer with head raised up, turned to the right, on a silver background.
