Vajra Symbolism in Austrian Cathedral

Viewing the high resolution version thru this link, you can see several mythological figures featured in the book.

Starting near the center, there is a winged figure holding something that looks like electricity which seems to be part of a crack in the ceiling. This is a vajra thunderbolt, which he is carrying downward to Earth. It represents the re-linking or "re-ligioning" of Heaven and Earth and the pathway to the gods.

Notice that he is coming from the figure on the right in the golden chariot and the vajra crack extends across the head of the green hydra on the left. The chariot is being driven by a Phrygian version of Venus named Cybele (note the Phrygian cap she wears), known in the Rig-Veda as Vena, who is described as carrying the Sun across the sky in a golden chariot. This description originates from the fact that Venus rises in the morning before the Sun (called the Morning Star) and seems to be lifting it up or resurrecting it. Her chariot is pulled by two lions considered guardians of the Underworld because they and Vena/ Cybele eventually carry the Sun into the dark Underworld at night.

The three-headed hydra, also described in Greek mythology as guards of the entrance to heaven, is being slain by Heracles. This was his twelfth and last labor. To the Phoenicians, Heracles was named Melqart and associated with the Sun. Melqart also had a son named Iesous, who was one of a long line of entheogenic vegetation gods corresponding to the Vedic Soma moon god. Iesous appears in Dr. Savin's first vision in the book.

All together, these mythical Greek themes can be traced back to the Rig-Veda, humanity's oldest written religious scripture.
