An inscription reading simply ""alu"" is found on a stone discovered in a grave mound located by the farm of Elgesem, Vestfold, Norway, in 1870. The Elgesem runestone, listed in the Rundata catalog as N KJ57 U, is dated to about 400 CE. The stone is 172 centimeters tall and 90 centimeters wide, and the thickness is about 18 centimeters. The inscription is written counter-clockwise and is to be read from the top downwards. As the stone has been purposefully shaped, it has been suggested that the Elgesem runestone was a cult stone used as part of some ritual. It has also been suggested that similar shaped cult stones are depicted on the Stora Hammars I, Ardre VIII and Tängelgårda IV image stones.
