The Blog about painting and computers,especially AI,sketched a possible future of painting,whereby digital and human artists will cooperate.In that respect it is also interesting to know what the possible origins of painting are.
Probably painting originated in ancient caves as a means of communication before human language was developed.

Cave paintings are found on the wall or ceilings of caves. The term usually impliesprehistoric origin, but cave paintings can also be of recent production: In the Gabarnmung  cave of northern Australia, the oldest paintings certainly predate 28,000 years ago, while the most recent ones were made less than a century ago.

The oldest known cave paintings are over 40,000 years old , found in both the Franco-Cantabrian region in western Europe, and in the caves in the district of Maros (Sulawesi, Indonesia). The oldest type of cave paintings are hand stencils and simple geometric shapes; the oldest undisputed examples of figurative cave paintings are somewhat younger, close to 35,000 years old. A 2018 study claimed an age of 64,000 years for the oldest examples of (non-figurative) cave art in Iberia, which would imply production by Neanderthals rather than modern humans. In November 2018, scientists reported the discovery of the oldest known figurative art painting, over 40,000 (perhaps as old as 52,000) years old, of an unknown animal, in the cave of Lubang Jeriji Saléh on the Indonesian island of Borneo

Let me conclude by saying that painting has come a long way and will stay for an unforseeable time as a means of expressing both the inner-and outer world of human beings.

In the meantime I enjoy painting my way and end this Blog with my own little cave drawing,together with a Haiku,resuming a famous Zen story about the Bull as metaphor for the eternal principle of life.Painting proved to be my way of taming the bull.
