It has often been reported that animals are attracted to saints, yogis, people meditating or in samadhi, etc. Wayne Wirs gives an example in this blog post:
Saint Francis and Ramana Maharshi are famous examples -- Lakshmi the cow, etc.
And check out this picture of our poetry editor with Rocky the squirrel:

I used to live with a cat who would come lie on me like a sphinx when I meditated and remain motionless, purring without interruption until I finished, even if it went on for hours.
Reason I bring this up is that I just ran across a picture of the Gundestrup Cauldron, an Iron-age artifact. The antlered figure is usually taken to be Cernunnos, a Celtic god.
His eyes seem to be closed; he looks like a yogi. The deer on his right and hound on his left, natural enemies, seem to be at peace due to his influence.
A Celtic yogi? This cauldron was dug up in Denmark.
