The oldest finds in Europe: what miners discovered in Spain's Bat Cave (photos).

In a cave near Granada, Spain, ancient artifacts over 7,000 years old have been discovered. Among the findings are the oldest bowstrings in Europe and feathered arrows, showcasing advanced weapon-making technologies of prehistoric communities in southern Iberia, writes IFLScience.

These Stone Age items, unearthed by miners in the 19th century, were intentionally buried alongside human remains in the Bat Cave (Cueva de Los Murciélagos). Thanks to the dry conditions of the cave, which prevented decay, these artifacts have remarkably well-preserved.

Two bowstrings were made from the tendons of various animals, including goats, wild boars, and deer. The study's author, Raquel Piqué, noted that this method allowed for the creation of strong and flexible ropes, reflecting the technical expertise of these early craftsmen.

The bowstrings, described as "S-shaped twisted cords," had a thickness ranging from three to four centimeters and were designed for strength and elasticity. Similar bowstrings were previously associated with the famous Alpine mummy Ötzi, highlighting the ingenuity of prehistoric cultures.

For the arrows, olive and willow wood, as well as reeds, were used. Olive wood provided strength and durability, while willow offered a lighter option for faster projectiles. The reed arrow with attached feathers is the oldest feathered arrow found in Europe.

This discovery raises questions about the societal role of such sophisticated weapons during the Neolithic era. Further study of the characteristics of this ancient weapon may shed light on its use, whether for hunting, warfare, or rituals.
