Per my research Krishna is the equivalent of Dionysus-Osiris. I found a story about the Nagas that is quite interesting. There was a dangerous, poisonous Naga who lived in a river. Krishna stepped on it to retrieve a ball and the serpent tried to kill him by wrapping around him. Krishna became so large, the serpent had to let him go. Look at these depictions:
Krishna dancing over the subdued Kaliya Naag, and his wives asking Krishna for his mercy. From a Bhagavata Purana manuscript, c. 1640.
It is further said that the Nagas were at one point cousins to their enemy Garuda (shown as a giant eagle which is the symbol of Zeus).
The proper home of Kāliya was Ramanaka Dwipa, but he had been driven away from there by fear of Garuda, the foe of all serpents. Garuda had been cursed by a yogi dwelling at Vrindavan so that he could not come to Vrindavan without meeting his death. Therefore Kāliya chose Vrindavan as his residence, knowing it was the only place where Garuda could not come.
Now what does this story sound like?
Genesis 3:15 – And I will put enmity between you and the woman, and between your offspring and hers; he will crush your head, and you will strike his heel.
It appears that this Naga may represent Prometheus-Set-Lucifer and/or his bloodline, Krishna would be Dionysus-Osiris or his bloodline, and Garuda is Zeus (and all of his bloodline) if all of this is symbolic of the story of the Cronides. Once again an elixer of the Gods is given to the Nagas to make a truce, which is a concept found in Greek mythology. Per Wikipedia:
The great nemesis of the nagas in the Mahabharata is the gigantic eagle-king Garuda. Garuda and the nagas began life as cousins. The sage Kasyapa had two wives (amongst his 13 wives, all prajapati Daksha’s daughters), Kadru and Vinata, the former of whom desired many offspring, and the latter of whom desired few but powerful offspring. Each got her wish. Kadru laid 1000 eggs which hatched into snakes, and Vinata laid two, which hatched into the charioteer of Surya the sun god and Garuda. Through a foolish bet, Vinata became enslaved to her sister, and as a result Vinata’s son Garuda was required to do the bidding of the snakes. Though compliant, he chafed and built up a grudge that he would never relinquish. When he asked the snakes what he would have to do in order to release his mother, Vinata, from her bondage, they told him he would have to bring them amrita, the elixir of immortality.Garuda stole the elixir from the gods and brought it to the serpents in fulfillment of their requirement, but through a ruse prevented them from partaking of it and achieving immortality. From that point onward, he regarded them as enemies and as food. (Book I: Adi Parva, Sections 16ff.)
The Brahminy Kite (top) is considered as the contemporary representation of Garuda. Garuda may be also identified with an eagle. Vishnu riding Garuda, depicted as a complete bird in this painting by Raja Ravi Varma (bottom).
