In a long letter to W.B. Yeats just before his death, Sharp gives a beautifully poetic allegory of the wind, the match and the flame. I will quote this letter in its entirely at a later point. The most nature-wrought of the English poets hoped he was not too late in transmuting into his own verse something of the beautiful mythology of Greece. I will have more to say about Rinder's role later. Before continuing, I think it is important to have a working definition of what I mean by the term mystic.
Mystical literature belongs to the mystics.
It has grown up out of a struggle to achieve clarity. According to Borchert's definition of mystic, I could make a case for qualifying and I could make the same claim for Sharp. Borchert does not mention Celtic mysticism in his book, a common oversight by many scholars. The reason for this is because up until the nineteenth century when excavations in Austria and Switzerland revealed Celtic treasures, the Celts where considered the barbarians of Europe. Prior to this reevaluation, the ideas and products of the Celts were considered as valueless as those of Native American Indians.
