Hibbert Lectures, and in his later masterly work on _The Arthurian
Legend_, however, he took the standpoint of the "mythological" school,
and tended to see in the old stories myths of the sun and dawn and the
darkness, and in the divinities sun-gods and dawn-goddesses and a host
of dark personages of supernatural character. The present writer,
studying the subject rather from an anthropological point of view and in
the light of modern folk survivals, has found himself in disagreement
with Sir John Rh[^y]s on more than one occasion. But he is convinced
that Sir John would be the last person to resent this, and that, in
spite of his mythological interpretations, his Hibbert Lectures must
remain as a source of inspiration to all Celtic students. More recently
the studies of M. Salomon Reinach and of M. Dottin, and the valuable
little book on _Celtic Religion_, by Professor Anwyl, have broken fresh
ground.[1]

In this book I have made use of all the available sources, and have
endeavoured to study the subject from the comparative point of view and
in the light of the anthropological method. I have also interpreted the
earlier cults by means of recent folk-survivals over the Celtic area
wherever it has seemed legitimate to do so. The results are summarised
in the introductory chapter of the work, and students of religion, and
especially of Celtic religion, must judge how far they form a true
interpretation of the earlier faith of our Celtic forefathers, much of
which resembles primitive religion and folk-belief everywhere.

Unfortunately no Celt left an account of his own religion, and we are
left to our own interpretations, more or less valid, of the existing
materials, and to the light shed on them by the comparative study of
religions. As this book was written during a long residence in the Isle
of Skye, where the old language of the people still survives, and where
