Two Horses - Two Stone-Age Worlds

Wild Horse Figurine, ca. 35,000 BC - Hunting Scene, ca. 17,000 BC

Comment
Both images stem from the Late Stone Age, which lasted roughly from 50,000 to 10,000 years ago.
The horse on the left dates from ca. 35,000 BC. It is one of eleven small ivory figurines, discovered in 1931 in the Vogelherd Cave in Germany, & ranks "among the oldest uncontested works of art of mankind" (Wikipedia). It was declared a UNESCO World Heritage Site in 2017.
On the right, a detail from one of the 600 large mural fresco paintings in the famous Lascaux Caves near the Dordogne River in France. Created some 19,000 years ago now, they were discovered in 1940, & added to the UNESCO Register already in 1979.
