Pan, the best friend of Dionysus, with numerous love adventures with the Nymphs, the most important of which was the seduction of Selyni.
He is the personification of the genetic power of life, and shows a cheerful character, but when needed he does serious work.
He is almost always illustrated with the wind instrument that he played, the flute.
In the battle of Marathon he helped the Greeks very much.
During the battle, he started shouting strong and terrifying cries and rhythmically, repeating "Pan Pan Pan".
Τhe Persians where overwhelmed by panic and retreated.
It is said that the word panic derives from Pan and his rhythmic cries.
