§ Akallabêth The Silmarillion

Thus the bliss of Westernesse became diminished; but still its might and splendour increased. For the kings and their people had not yet abandoned wisdom, and if they loved the Valar no longer at least they still feared them. They did not dare openly to break the Ban or to sail beyond the limits that had been appointed. Eastwards still they steered their tall ships. But the fear of death grew ever darker upon them, and they delayed it by all means that they could; and they began to build great houses for their dead, while their wise men laboured unceasingly to discover if they might the secret of recalling life, or at the least of the prolonging of Men's days. Yet they achieved only the art of preserving incorrupt the dead flesh of Men, and they filled all the land with silent tombs in which the thought of death was enshrined in the darkness. But those that lived turned the more eagerly to pleasure and revelry, desiring ever more goods and more riches; and after the days of Tar-Ancalimon the offering of the first fruits to Eru was neglected, and men went seldom any more to the Hallow upon the heights of Meneltarma in the midst of the land.
