Now let us have a look at that other aspect of initiation: the happy and sad king Arthur. […] These two faces of the king, one happy, the other one sad, to me show a similarity with the two figures of Saint John from the folk tradition. Guénon already pointed to the fact that the expresssion ‘John who cries and John who laughs‘ is no longer understood by the people. Yet there is a close connection to the initiatory tradition of the West that is connected to the initiative God Janus. The two saints that the folk traditions speaks of are John (Johannes) the Baptist and John the Evangelist. We can derive the name Johannes from the Hebrew word containing ‘hanan‘. This means ‘mercy‘ as well as ‘praise‘. ‘Jahanan‘ can thus be translated with ‘mercy of God‘ and ‘praise to God‘. In Christian spirituality Saint John has frequently been associated with the esoteric tradition, a hidden doctrine. Definately there are many references to cosmic symbolism. […] Compared the the Christian calendar, the figures of John the Baptist and John the Evangelist equate with Janua Inferni and Janua Coeli from the Roman tradition. The initiative God Janus – who has two faces, one looks back the other forward – holds in his hands the keys to the gates of the solstices. He is the Janitor, he who opens and closes. The paths of Janua Inferni and Janua Coeli would etymologically and symbolically relate to the Indian Pitri-yana and DevÍ¢-yana, the path of the ancestors and the path of the Gods. One – that of the ancestors – leads from summer solstice (John the Baptist) to winter solstice (John the Evangelist), the other – that of the Gods – leads from winter solstice to summer solstice.
