Pan is usually represented in the form of a satyr, with goat's horns and a cloak of goat's skin, playing the Syrinx, or flute of seven pipes, and holding the pedum or pastoral staff. Pan was in love with the chaste nymph Syrinx. She sought help from her fellow river-nymphs and was transformed into reeds, a plant with a hollow stem. The reeds made a strong sound when the angry Pan was breathing upon them. He cut them and invented the syrinx (pan-flute).
