Among the royal heirlooms of the Kings of Númenor was the Bow of Bregor. It was used to shoot black-feathered arrows that were a full ell long from point to notch. 'The Men of the Sea,' it was said, 'send before them a great cloud, as of rain turned to serpents, or a black hail tipped with steel.''. 'In later days, in the wars upon Middle-Earth, it was the bows of the Númenóreans that were most greatly feared. Númenóreans used a type of bow called the steel-bow, which was made of hollow steel, as its name implies.Elves were the first race to develop and master the use of bows, and later passed their knowledge to Men. Elves of Doriath and Lothlórien used longbows which were, as their name suggests, longer bows which could shoot farther and higher than any other types of bows.It is said in a poem that Eärendil wielded a bow 'made of dragon-horn'. While Elven flawless bows were made from wood, Númenórean bows were made of hollow steel, forged in armories.
