Somatics in the Druid Tradition

My question is did the ancient druids have a somatic practice such as yoga or mudras?

Maybe this can be learned from the Akashic Archives.

Maybe the painting of blue designs on their skin counted as somatic. I bet it was done as part of ritual.

Also, the oghams had a secret sign language as part of it that got banned because it made the Druids too powerful. They would touch their nose or their leg or a straight surface.
