§ Akallabêth The Silmarillion

Thus it was that because of the Ban of the Valar the voyages of the Dúnedain in those days went ever eastward and not westward, from the darkness of the North to the heats of the South, and beyond the South to the Nether Darkness; and they came even into the inner seas, and sailed about Middle-earth and glimpsed from their high prows the Gates of Morning in the East. And the Dúnedain came at times to the shores of the Great Lands, and they took pity on the forsaken world of Middle-earth; and the Lords of Númenor set foot again upon the western shores in the Dark Years of Men, and none yet dared to withstand them. For most of the Men of that age that sat under the Shadow were now grown weak and fearful. And coming among them the Númenóreans taught them many things. Corn and wine they brought, and they instructed Men in the sowing of seed and the grinding of grain, in the hewing of wood and the shaping of stone, and in the ordering of their life, such as it might be in the lands of swift death and little bliss.
