The Druids are an interesting religion to study. In fact, I have found more relationships between different Druid rituals and annual holidays associated with the Christian faith. An important thing anyone should know about the Druids before studying them is there are no written records of their rituals, where they came from, or when they began. They did not have any way of writing down what happened in their culture at specific times for specific reasons. They preferred to hand down stories and rituals by mouth, or legend if you will. Many sources of information about the Druids have been written, but only few hold water. The earliest account of the Druids in written record was during second century B.C., when Julius Caesar began to conquer Europe. An interesting fact is the Druids have inhabited Europe for the better part of three millennia prior to Caesar's first contact. Most of the information, with the exception of ancient literature, is very bias and pro-Christian. Nevertheless, through some hard digging, I have found an interesting ritual and practice the Druids performed, and are most known for, divination.
The Druids, for all-important matters that faced the Celts, practiced the art of divination "forecasting future events. This art included mainly of observing natural objects (such as clouds) or occurrences, and also by certain artificial rites. In all aspects, it is said a Druid is a fáith or profit, not a religion. .
Observations of clouds was one of the many ways of receiving omens. Dathi, king of Ireland (A.D. 405-428), told his Druid, on the sacred night of November first, to read his future for the next year. The Druid did as he was commanded, and went to the top of "the druids' hill,"" called Mullaroe, often called Red Hill, which is not its name, and he stayed there all night. He returned to the king the next morning and said, "Art thou asleep, O King of Erin and Alban (Scotland)?- "Why the addition to my Title?- asked the king.
