“And when Melkor saw that these lies were smouldering, and that pride and anger were awake among the Noldor, he spoke to them concerning weapons; and in that time the Noldor began the smithying of swords and axes and spears. Shields also they made displaying the tokens of many houses and kindreds that vied one with another; and these only they wore abroad, and of other weapons they did not speak, for each believed that he alone had received the warning.” Silm., “Of the Silmarils and the Unrest of the Noldor,” 69.
