No one knows the name of the magic flower of
Greek legend that Flora gave to the goddess Juno to make her pregnant.
According to the myth, Juno was jealous about the birth of the goddess
Athena without a mother and was determined to have a child by herself.
(Athena's father, Zeus, had swallowed his pregnant wife Metis, because he
feared she would give birth to a son stronger than himself; Athena sprang
from the head of her father when the god Prometheus split his head open
with an axe.) Flora's magic flower enabled Juno to have a child without a
father, and she gave birth to Mars, who was a god of vegetation, sacred to
farmers, and later became the god of war.
