Picturile rupestre din China au fost conservate cu sânge

A new study reveals how the Luoyue people created durable rock paintings in southern China, using blood as a key ingredient in their paint. These ancient artworks, dating back nearly 2,000 years, have remarkably survived harsh environmental conditions. Researchers analyzed samples from various sites and found that the paintings were made using a mixture of animal bones, bird droppings, and blood, which helped bond the pigments to the rock. The presence of human blood, particularly from pregnant women, suggests a cultural significance related to fertility. However, some experts question the findings, citing potential contamination and the need for further research.
