Peat preserves timber, animals, and such unexpected treasure-troves as hoards of acorns and firkins of beech butter from the forests which preceded the bogs. A whole archaeology may very well lie in peat, and the pollen record may reveal past history. At the base of Irish bogs the Fir Bolg (the little people), their axes, bridges, butter, and forest life are well preserved. They and their forests were banished, as if by magic, by the Tuatha de Danan (the Children of Diana) who now dig the peat. Diana was displaced in turn by Mary, mother of God. But all are mixed in the peat and the tongue of Ireland.
