Just read on the net:
Af means the sound of the dog’s bark and Ghan means the raven(black crow). Could easily have meant loyal Ravens or something to get into the right books of the Sun God…!
According to what we have found till now, Raven is the bird that the word A-RAb also means. And raven is famous for being associated with the Sun God from ages. Perhaps India’s KaaNvarrs are that too_getting water for the Sun as the raven had once not brought it for the Sun God when he ASKED for it and so became black by the Sun God’s punishment(used to be white earlier!), and got a bad voice and was also banished to the skies where it is as a star formation etc.
We don’t believe in myths and don’t worship them etc but just want to trace the history of beliefs..
