The Kalevide now decided on a journey north, to the uttermost end of the world, where it touches the sky. He imagined that he could only reach this point by sea, and thought at first of travelling on the wings of an eagle. Meantime, a raven directed him, when he came to a broad expanse of blue water, to look for a place where rushes grew on the bank, and to stamp on the ground with his right foot, when the mouth of the earth and the strongly guarded doors would fly open, and he would reach the end of the world. Then the Kalevide reflected how he had waded through every lake and sea, and had found none too deep for him except Lake Ilma. He then thought he would visit Finland, Norway, and the islands, where he expected to find old friends to direct him on his journey. So he directed Olev [Pg 111] to fell the great oak-tree which their father and mother had planted, and which neither sun, moon, stars, nor rain, could penetrate, [82] and to make the strongest sailing vessels for exploring voyages from the trunk, warships from the crown, merchantmen from the large branches, slave-ships from the smaller ones, children's boats from the splinters, and maiden's boats from the chips. He ordered the remainder to be used for building towns, fortresses, and houses for the people in various parts of the country. Olev replied, "I know what to do, dear brother, if we can find a strong man in the country able to fell the oak-tree." The raven told them to send out to seek for such a man, and they did so; whereupon the wise men of Norway and Finland assembled to give them advice. But they told the Kalevide that it was no use building a wooden ship to sail to the world's end, for the spirits of the Northern Lights would set it in flames. He must build a strong vessel of iron and copper and tin. The Kalevide then constructed a vessel, not of [Pg 112] iron and copper, but of silver. The whole of the ship—planking, deck, masts, and chains—was of silver, and he named the vessel Lennuk. [83] For himself he provided golden armour, silver for the nobles, iron for the crew, copper for the old men, and steel for the wise men. The Kalevide selected experienced sailors and many wise men to accompany him, and they set sail joyfully towards Finland; but soon turned, and directed their course to the far north, in the direction of the Great Bear.
