Pan from the book Greece and Rome by H.A.Guerber

    Pan was equally devoted to music, the dance, and pretty nymphs. He saw one of the nymphs, Syrinx whom he immediately loved; but unfortunately for him she, frightened at his appearance, fled. Exasperated by her persistent avoidance of him, Pan once pursued and was about to overtake her, when she paused, and implored Gaea to protect her. The prayer was scarcely ended, when she found herself changed into a clump of reeds, which the panting lover embraced, thinking he had caught the maiden, who had stood in that very spot a few minutes before.
    His deception and disappointment were so severe that they wrung from him a prolonged sigh, which, passing through the rustling reeds, produced plaintive tones. Pan, seeing Syrinx had gone forever, took seven pieces of the reed, of unequal lengths, bound them together, and fashioned from them a musical instrument, which was called by the name of the fair nymph.
    Pan was supposed to delight in slyly overtaking belated travellers and inspiring them with sudden and unfounded fears, -from him called "panic." He is generally represented with a syrinx and shephard's crook, and a pine garland around his misshapen head.
