The term druid means very knowledgeable and druids were seen as members of an exclusive occupational class. It is generally accepted that the druid was a sort of intermediary and had direct connections with the otherworld. A druid's opinion was always sought on matters of law and tradition. They could identify thieves, interpret dreams, cure illnesses and give shrewd military advice. The druid was believed to possess mystical powers and in Irish tradition the term bard is more often used for leading figures such as a poet whose verse was believed to have magical connotations. The teachings of the druid were based on the five elements: earth, sea, sky, sun and moon.
