Sonnet Written upon the Top of Ben Nevis

Read me a lesson, Muse, and speak it loud
Upon the top of Nevis, blind in mist!
I look into the chasms, and a shroud
Vapourous doth hide them, — just so much I wist
Mankind do know of hell; I look o'erhead,
And there is sullen mist, — even so much
Mankind can tell of heaven ; mist is spread
Before the earth, beneath me, — even such,
Even so vague is man's sight of himself!
Here are the craggy stones beneath my feet, —
Thus much I know that, a poor witless elf,
I tread on them, — that all my eye doth meet
Is mist and crag, not only on this height,
But in the world of thought and mental might !
