Celticii si-au transmis cultura din vorba in vorba, prin povestiri si mituri, niciodata nu au scris istoria sau faptele lor. This accounts for the extreme lack of knowledge about them prior to their contact with the classical civilizations of Greece and Rome. They were generally well educated, particularly on topics such as religion, philosophy, geography and astronomy. The Romans often employed Celtic tutors for their sons, many of these tutors were Druid priests. Religion was a force in Celtic culture. The Druids were their priestly caste. The Celts were extremely superstitious.
