The article deals with a monogram of Henry Kietlicz, archbishop of Gniezno (1199-1219). It is known only from the rota on a document of Henry the Bearded of 1208. In literature the monogram was rendered as hEnRIC(US) but the present article shows a possibbility of a different reading, namely PETRC(US). The monogram PETRC(US) may have been inspired by the monogram PETRUS, known from the iconography of St. Peter. This PETRC(US) monogram and other symbols used by the archibishop may indicate that Henry Kietlicz was forming his own image imitating that of the pope (imitatio papae).
