Boyhood of Columbus

I know not when this hope enthralled me first,
But from my boyhood up I loved to hear
The tall pine-forests of the Apennine
Murmur their hoary legends of the sea,
Which hearing, I in vision clear beheld
The sudden dark of tropic night shut down
O'er the huge whisper of great watery wastes,
The while a pair of herons trailingly
Flapped inland, where some league-wide river hurled
The yellow spoil of unconjectured realms
Far through a gulfs green silence, never scarred
By any but the North-wind's hurrying keels.
And not the pines alone; all sights and sounds
To my world-seeking heart paid fealty,
And catered for it as the Cretan bees
Brought honey to the baby Jupiter,
Who in his soft hand crushed a violet,
Godlike foremusing the rough thunder's gripe;
Then did I entertain the poet's song,
My great Idea's guest, and, passing o'er
That iron bridge the Tuscan built to hell,
I heard Ulysses tell of mountain-chains
Whose adamantine links, his manacles,
The western main shook growling, and still gnawed;
I brooded on the wise Athenian's tale
Of happy Atlantis, and heard Bjorne's keel
Crunch the gray pebbles of the Vinland shore:
For I believed the poets; it is they
Who utter wisdom from the central deep,
And, listening- to the inner flow of things,
Speak to the age out of eternity.
