The art of the dance hath given me as many different steps as a night deadly with storms maketh waves upon the sea.

Suidas Lexicon

Nightingale:
Hail, motley Muse of green and glade, Jug, jug, tereu, Who, as on leafy ash I sit By hill or dale to music it, Tereu, tereu, dost lend thine aid, While through my brown beak I recite Sacred songs for Pan's delight, And to the Mountain-Mother bring High dance-music for offering, Tereu, tereu, Whence Phrynichus sipt like a bee, Ambrosial brew, A harvest of sweet melody, Jug, jug, tereu.

Aristophanes Birds

“Yet Phrynichus the tragedy-writer says of himself:”
