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 Brygdæa 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 hällristningar, or rock-sculptures. Holmberg has figured many of them in his interesting work entitled Scandinaviens Hällristningar. At Lökeberg 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.
In not a few places in our own country and on the Continent, rough misshapen marks on rocks and stones, bearing a fanciful resemblance to the outline of the human foot, have been supposed by popular superstition to have been made by Satan. Every classical student is familiar with the account which Herodotus gives of the print of Hercules shown by the Scythians in his day upon a rock near the river Tyras, the modern Dnieper. It was said to resemble the footstep of a man, only that it was two cubits long. He will also recall the description given by the same gossipy writer of the Temple of Perseus in the Thebaic district of Egypt, in which a sandal worn by the god, two cubits in length, occasionally made its appearance as a token of the visit of Perseus to the earth, and a sign of prosperity to the land. Pythagoras measured similar footprints at Olympia, and calculated "ex pede Herculem"! Still more famous was the mark on the volcanic rock on the shore of Lake Regillus—the scene of the memorable battle in which the Romans, under the dictator Posthumius, defeated the powerful confederation of the Latin tribes under the Tarquins. According to tradition, the Roman forces were assisted by Castor and Pollux, who helped them to achieve their signal victory. The mark was supposed to have been left by the horse of one of the great twins "who fought so well for Rome," as Macaulay says in his spirited ballad. On the way to the famous convent of Monte Casino, very near the door, there is a cross in the middle of the road. In front of it a grating covers the mark of a knee, which is said to have been left in the rock by St. Benedict, when he knelt there to ask a blessing from heaven before laying the foundation-stone of his convent. As the site of the monastery was previously occupied by a temple of Apollo, and a grove sacred to Venus, where the inhabitants of the surrounding locality worshipped as late as the sixth century,—to which circumstance Dante alludes,—it is probable that the sacred mark on the rock may have belonged to the old pagan idolatry, and have been a cup-marked stone connected with sacrificial libations.
On many rocks of the United States of America may be seen human footprints, either isolated or connected with other designs belonging to the pictorial system of the Aborigines, and commemorating incidents which they thought worthy of being preserved. In the collection of the Smithsonian Museum are three large stone slabs having impressions of the human foot. On two slabs of sandstone, carefully cut from rocks on the banks of the Missouri, may be seen respectively two impressions of feet, carved apparently with moccasins, such as are worn at the present day by the Sioux and other Indians. The other specimen is a flat boulder of white quartz, obtained in Gasconade County, Missouri, which bears on one of its sides the mark of a naked foot, each toe being distinctly scooped out and indicated. The footmark is surrounded by a number of cup-shaped depressions. In many parts of Dacotah, where the route is difficult to find, rocks occur with human footprints carved upon them which were probably meant to serve as geographical landmarks—as they invariably indicate the best route to some Indian encampment or to the shallow parts of some deep river. Among other places these footprints have been met with on the Blue Mountains between Georgia and North Carolina, and also on the Kenawha River. Some stir was made two years ago by the reported discovery of the prints of human feet in a stone quarry on the coast of Lake Managua in Nicaragua. The footprints are remarkably sharp and distinct; one seems that of a little child. The stone in which they are impressed is a spongy volcanic tuff, and the layer superimposed upon them in the quarry was of similar material. These prehistoric footprints were doubtless accidentally impressed upon the volcanic stone, and would seem to throw back the age of man on the earth to a most remote antiquity. In Equatorial Africa footprints have also been found, and are associated with the folklore of the country. Stanley, in his Dark Continent, tells us that in the legendary history of Uganda, Kimera, the third in descent from Ham, was so large and heavy that he made marks in the rocks wherever he trod. The impression of one of his feet is shown at Uganda on a rock near the capital, Ulagolla. It was made by one of his feet slipping while he was in the act of hurling his spear at an elephant. In the South Sea Islands department of the British Museum is an impression of a gigantic footstep five feet in length.
The connection of prehistoric footprints with sacred sites and places of sepulture would indicate that they had a religious significance—an idea still further strengthened by the fact of their being frequently associated with holy wells and groves, and with cup-shaped marks on cromlechs or sacrificial altars, which are supposed to have been used for the purpose of receiving libations; while their universal distribution points to a hoary antiquity, when a primitive natural cultus spread over the whole earth, traces of which are found in every land, behind the more elaborate and systematic faith which afterwards took its place. They are probably among the oldest stone-carvings that have been left to us, and were executed by rude races with rude implements either in the later stone or early bronze age. Their subsequent dedication to holy persons in Christian times was in all likelihood only a survival of their original sacred use long ages after the memory of the particular rites and ceremonies connected with them passed away. A considerable proportion of the sacred marks are said to be impressions of the female foot, attributed to the Virgin Mary; and in this circumstance we may perhaps trace a connection with the worship of the receptive element in nature, which was also a distinctive feature of primitive religion.
It is strange how traces of this primitive worship of footprints survive, not merely in the mythical stories and superstitious practices connected with the objects themselves, but also in curious rites and customs that at first sight might seem to have had no connection with them. The throwing of the shoe after a newly-married couple is said to refer to the primitive mode of marriage by capture; but there is equal plausibility in referring it to the prehistoric worship of the footprint as a symbol of the powers of nature. To the same original source we may perhaps attribute the custom connected with the Levirate law in the Bible, when the woman took off the shoe of the kinsman who refused to marry her, whose name should be afterwards called in Israel "the house of him that hath his shoe loosed."
In regard to the general subject, it may be said that we can discern in the primitive adoration of footprints a somewhat advanced stage in the religious thoughts of man. He has got beyond total unconsciousness of God, and beyond totemism or the mere worship of natural objects—trees, streams, stones, animals, etc. He has reached the conception of a deity who is of a different nature from the objects around him, and whose place of abode is elsewhere. He worships the impression of the foot for the sake of the being who left it; and the impression helps him to realise the presence and to form a picture of his deity. That deity is not a part of nature, because he can make nature plastic to his tread, and leave his footmark on the hard rock as if it were soft mud. He thinks of him as the author and controller of nature, and for the first time rises to the conception of a supernatural being.
