So common are the curious sculptures under consideration in Norway and Sweden, that they are known by the distinct name of Fotsulor, or Footsoles.  They are marks of either naked feet, or of feet shod with primitive sandals.  On a rock at Brygdaea in Westerbotten, in Norway, there are no less than thirty footmarks carved on a rock at an equal distance from each other.  In other parts of Norway these footprints are mixed up with rude outlines of ships, wheels, and other haellristningar, or rock-sculptures.  Holmberg has figured many of them in his interesting work entitled Scandinaviens Haellristningar.  At Loekeberg Bohnslau, Sweden, there is a group of ten pairs of footmarks, associated with cup-shaped hollows and ship-carvings; and at Backa, in the same district, several pairs of feet, or rather shoe-marks, are engraved upon a rock.  In Denmark not a few examples of artificial foot-tracks have been observed and described by Dr. Petersen.  One was found on a slab belonging to the covering of a gallery in the inside of a tomb in the island of Seeland, and another on one of the blocks of stone surrounding a tumulus in the island of Laaland.  In both cases the soles of the feet are represented as being covered; and in all probability they belong to the late stone or earlier bronze age.  With these sepulchral marks are associated curious Danish legends, which refer them to real impressions of human feet.  The islands of Denmark were supposed to have been made by enchanters, who wished for greater facilities for going to and fro, and dropped them in the sea as stations or stepping-stones on their way; and hence, in a region where the popular imagination poetises the commonest material objects, and is saturated with stories of elves and giants, with magic swords, and treasures guarded by dragons, it was not difficult to conclude that these mysterious foot-sculptures were made by the tread of supernatural beings.  Near the station of Sens, in France, there is a curious dolmen, on one of whose upright stones or props are carved two human feet.  And farther north, in Brittany, upon a block of stone in the barrow or tumulus of Petit Mont at Arzon, may be seen carved an outline of the soles of two human feet, right and left, with the impressions of the toes very distinctly cut, like the marks left by a person walking on the soft sandy shore of the sea.  They are surrounded by a number of waving circular and serpentine lines exceedingly curious.  On Calais pier may be seen a footprint where Louis XVIII. landed in 1814; and on the rocks of Magdesprung, a village in the Hartz Mountains, a couple of hundred feet apart, are two immense footprints, which tradition ascribes to a leap made by a huge giantess from the clouds for the purpose of rescuing one of her maidens from the violence of an ancient baron.
