There were many "hippie movements" before in history, stressing liberty and nature and free spirituality.

Romanticism of the 17/18. century comes to mind. A trans-European movement in art (literture, painting, music, poetry, etc.) stressing transcendence in nature, the supernatural, personal freedom, individuality and liberty, also a focus on the power of imagination. It was a counter-culture to the age of 'rationality' and 'materialism' of that time.
