The spesific causality between micro and macrocosm is the key

The Celts – far from being a singular mass of wilds. There were no barbarians – were made up of diverse, distinct groups who battled numerous threats, from the Romans to the Normans.
Everybody's has heard swathed in myths and legends about The Celts.
When Greek explorer Pytheas of Massalia made a voyage of exploration to Britain over 300 years before Christ, he called the native peoples Pretanike or the people of the designs because of the crazy patterns that warriors painted on their skin.
These early Britons and their neighbours in Ireland all spoke some form of Celtic language by the fifth century bc.
Their nature-mystical religious beliefs, their gods and goddesses, laws and military methods, technology and art were common to all Celtic peoples, whose settlements extended from Galatia in modern Turkey, through central and Western Europe and the British Isles, all the way to Celt-Iberia constituting Spain and Portugal.
They have been even here in Finland.
But the Celts were intensely independent and tribal. Even within Britain, a host of separate and distinct tribes zealously guarded their ancestral territories, ruled by kings whose ultimate legitimacy was based on divine descent. The priest-magicians who guided these kings and their tribal peoples, the Druids, were described by Julius Caesar as having originated in Britain.
What made a Celt? The spirit of the half esoteric Christianity, said tri Rudolf Steiner.
We know very little about their culture, their music, their cultural sites. Almost everything comes from a period of decadence, Steiner continued.

The new study charts the history of the Celts. Future research will examine DNA and strontium isotopes from human bones from these sites to learn more about who built the world's megaliths, Schulz Paulsson said.
But we are still far from their cosmic understanding. This is the causality between micro and macrocosm.
Celtic peoples throughout Europe and Asia Minor shared common cultural, technological, legal and spiritual characteristics, and their languages were broadly similar.
In recent years, revisionist historians have sought to dismiss the traditional account of Celtic settlement, and indeed to disinvest the Celts as an authentic ethnicity with its own distinctive culture. No good.
There were three waves of Celtic immigrants from the continent arrived. The first one commencing around circa 400 BC. The secent wave 900 BC, were called Goidels or Gaels.
