Hartley Coleridge - The Birth of Speech lyrics

What was't awakened first the untried ear Of that sole man who was all human kind? Was it the gladsome welcome of the wind, Stirring the leaves that never yet were sere? The four mellifluous streams which flowed so near, Their lulling murmurs all in one combined? The note of bird unnamed? The startled hind Bursting the brake, in wonder, not in fear, Of her new lord? Or did the holy ground Send forth mysterious melody to greet The gracious pressure of immaculate feet? Did viewless seraphs rustle all around Making sweet music out of air as sweet? Or his own voice awake him with its sound?
