 The circumference of the pommel is decorated with a rhombic pattern , while the upper side of the crossguard – with a similar triangular pattern . The narrow sides of the grip used to be embellished with inscribed silver plates , which , however , were lost in the 19th century . These lost inscriptions are partly known from graphical documentation made by King Stanislaus Augustus 's court painter , Johann Christoph Werner , in 1764 and by Jacek Przybylski in 1792 . One of the plates had already been broken by that time with only part of the inscription preserved : Liste est <unk> ... h <unk> Duc ... ( " This is a sword of ... Duke Boleslaus ... " ) ; the inscription on the other plate continued : Cum quo ei D [ <unk> ] n [ us ] SOS [ Salvator <unk> Salvator ] <unk> ad [ ver ] sus partes amen ( " With whom is the Omnipotent Lord and Savior , to help him against his enemies . Amen " ) . The missing part of the first inscription is only known from an old replica of Szczerbiec which once belonged to the Radziwiłł family ( see Historical replicas below ) . The full inscription read : <unk> est gladius <unk> et <unk> <unk> <unk> Poloniae et <unk> , <unk> ( " This is a sword of Hereditary Prince Boleslaus , Duke of Poland , Masovia , and Łęczyca " ) . The identity of this Duke Boleslaus is uncertain .
