A treasury inventory of the Radziwiłł family's Nieśwież Castle (now Nesvizh in Belarus) made in 1740 includes a detailed description of a sword decorated with symbols of the Evangelists and inscriptions identical to those on Szczerbiec.
There are doubts, however, whether the swords known to have been at Żółkiew in 1738 and at Nieśwież two years later, were in fact the same sword.
