1. Prehistoric man

The concept of art therapy as a formal therapeutic practice is a relatively modern development. However, it is believed that prehistoric humans did engage in artistic expression, and some theories suggest that these artistic endeavours may have served therapeutic purposes.

While we can't definitively determine the motivations behind prehistoric art, some theories propose that creating art could have provided psychological benefits to early humans. These theories suggest that art might have served as a means of communication, storytelling, and ritualistic practises. Engaging in artistic activities could have provided an outlet for emotional expression, a way to connect with others, or even a means of coping with the challenges of their environment.

However, it's important to note that the concept of art therapy, as we understand it today, emerged much later. Art therapy as a formal practice started to gain recognition in the mid-20th century as mental health professionals began to explore the therapeutic benefits of artistic expression.
