After some more research on vultures i eventually unconvered some myths about their wing's having the ability to eclipse the moon and discovered the amazonian myth of Urubutsin the vulture god who was described as a horder of light and the king of all birds.
The myth of Urubutsin goes that he had all the light in the world and his minions wings blocked out any other light from touching the earth. Two brothers named Kuat and Iae who's tribe was in constant fear of attack from wild beasts due to the darkness decide to steal the light from Urubutsin. They hid themselves in a corpse and when Urubutsin came down to feed Kuat grabbed his leg preventing him from escaping forcing the king of birds to negotiate. He offers half of his light to the brothers in return for his freedom this light became the sun and the moon and it was agreed that day should alter with night. After this Kuat became associated with the sun and Iae the moon.

The story i decided on was one where Urubutsin tries to retieve the light that was taken from him by Kuat and Iae by harvesting it from their corpses which were being kept in a temple to solar deities in Italy. Disguising himself as a plauge doctor he enters the town where the temple is and enters the temple. Unknowingly to him another 2 brothers notice the suspicious plauge doctor and follow him to the temple and stop him after noticing the moonlight disappearing.
