Sacred Animals of Hera:
Cow - Hera was not fooled by the deception of Zeus during His affair with Io, when he turned Io into a cow to protect her from Hera. Hera devised a plan to get Io away from Zeus and to leave forever. Also, it is said that cows are a motherly animal and Hera chose the cow to be sacred to her. There are some that believe Hera was the one to turn io into a cow to punish her husband for the affair.
Peacock - It is said that Hera chose the peacock as sacred because she could see the eyes of Argos within them. Argos was a servant to Hera.
Sacred Plants of Hera:
Pomegranate - Hera chose the pomegranate due to its symbolism and relationship with marriages. Pomegranate was also a symbol of fertility. Her flower was the lily.
