Czupryna

One of Sachsenspiegel's illustrations. A Wend stands at the left, gesturing that he does not understand the speech. He has a halfshaven head and characteristically wrapped legs, like all the Wends in the Sachsenspiegel.
Henry I the Bearded and Jadwiga of Andechs wedding, 14th century Poles are on the left, with halfshaven heads. Medieval Poles didn't like long hair: Henry's beard was so strange to them that he was even called "the Bearded".

The czupryna (Polish: wysokie polskie cięcie, podgolony łeb, łaszczówka), also known as the Polish halfshaven head, is a traditional Polish noble haircut, associated mainly with Sarmatism, but worn by Poles in the Middle Ages too. It is marked by shaving hair above the ears and on the neck at the same height, with longer hair on the top of the head. For hundreds of years it was typical of Poles.
