Lecture XXXI
Achilles is invulnerable in his whole body with the exception of the heel, Siegfried with the exception of the spot between the shoulders. To be invulnerable in such a way signifies to have been initiated. In Achilles you have the initiate of the Fourth Sub-Race which lies on the ascending curve of man's cultural development: therefore all the upper parts of Achilles are invulnerable; only the heel the lower nature is vulnerable, just as Hephaistos is lame. The German Siegfried was also an initiate of the Fourth Sub-Race, but vulnerable between the shoulder blades. This is his vulnerable spot, first made invulnerable by the One who bore the cross. With Siegfried the Gods reach their downfall, the Northern Gods approach their end (Twilight of the Gods). This gives the Northern saga its tragic note, for it not only points to the past, but to the Twilight of the Gods, to the time which is to come. The Druids gave to man the teaching of the declining Northern Gods. Thus in what was still symbolic form, the battle of St. Boniface[^4] with the Oak represents the battle of the Druids with the old Priesthood.
