There are many refrences to the east wind in the story 'the birds' why is this significant? Do u think the author is using the east wind as a weather phenomena or is it a symbol of smth else?

I'm not sure about the specific text but in Greek mythology, Eurus, the east wind, was the only wind not associated with one of the three Greek seasons. Eurus is also the only one of these four Anemoi not mentioned in Hesiod's Theogony or in the Orphic Hymns.
