Note (return) — Chapter I

We have the surface observations of classical observers, dedications in the Romano-Celtic area to gods mostly assimilated to the gods of the conquerors, figured monuments mainly of the same period, coins, symbols, place and personal names. For the Irish Celts there is a mass of written material found mainly in eleventh and twelfth century MSS. Much of this, in spite of alteration and excision, is based on divine and heroic myths, and it also contains occasional notices of ritual. From Wales come documents like the Mabinogion, and strange poems the personages of which are ancient gods transformed, but which tell nothing of rite or cult.2 Valuable hints are furnished by early ecclesiastical documents, but more important is existing folk-custom, which preserves so much of the old cult, though it has lost its meaning to those who now use it. Folk-tales may also be inquired of, if we discriminate between what in them is Celtic and what is universal. Lastly, Celtic burial-mounds and other remains yield their testimony to ancient belief and custom.
