Two rib-bones with carvings depicting ships have recently been found in the central part of Sigtuna, one on the Urmakaren site and the other on the Professorn site. The Urmarkaren bone had on its reverse side a carving of a lion and the Professorn bone a complete, late-runic alphabet. The latter also had various triangular figures on both sides. Both finds can be dated to the 12th c. The authors suggest an interpretation of the bones within a Christian framework of symbols <e.g., the Trinity> and following a Nordic tradition in which a king may create loyalties by distributing wealth, such as ships. ;
