From Dawn to Noon

As the child knows not if his mother's face
Be fair; nor of his elders yet can deem
What each most is; but as of hill or stream
At dawn, all glimmering life surrounds his place:
Who yet, tow'rd noon of his half-weary race,
Pausing awhile beneath the high sun-beam
And gazing steadily back,--as through a dream,
In things long past new features now can trace:--

Even so the thought that is at length fullgrown
Turns back to note the sun-smit paths, all grey
And marvellous once, where first it walked alone;
And haply doubts, amid the unblenching day,
Which most or least impelled its onward way,--
Those unknown things or these things overknown.
