Półkozic - is a Polish coat of arms. It was used by several szlachta families in the times of the Polish-Lithuanian Commonwealth.
According to legend, this coat was assigned to knight Stawisz, who was defending the foreign castle of Etecz (or Eczech) against the pagans. When besieged, he ordered to kill a goat and a donkey, and then use their blood to paint ox's hide. With this hide he then ordered to decorate the walls of the castle. The pagans, seeing that defenders had so much meat as to waste it, lifted the siege and left. The knight was rewarded by the king Bolesław I Chrobry with a coat of arms and returned to Poland.
The bearers of the coat were mentioned since early Piast era. Initially they were tied to the land of Lesser Poland, (regions of Sandomierz and Kraków), regions near Lublin, Rawa Mazowiecka, Sieradz and then Red Ruthenia. After the Union of Horodło bearers of the coat of arms appeared also in Lithuania.
