Hello. I've just finished one of the lectures and there was mentioned Tetramorph and it's relation to the elements. It was said that lion is fire, bull is earth, eagle is air and human is water. It seems logical, that the eagle as a bird should be associated with air. However, some sources I studied in the past compared the animals with zodiac, being: lion as Leo, bull as Taurus, eagle as Scorpio and human as Aquarius. And the thing is that Scorpio has water nature and Aquarius - air. The elements/animals were also compared with Archangels. I checked, and it perfectly matched the name-element relation. So, the only different is the animal-element relation. My question is: which version is correct? And why?
