Untimely

Nothing in life has been made by man for man's using 
But it was shown long since to man in ages 
Lost as the name of the maker of it, 

Who received oppression and shame for his wages - 
Hate, avoidance, and scorn in his daily dealings - 
Until he perished, wholly confounded.  

More to be pitied than he are the wise 
Souls which foresaw the evil of loosing 
Knowledge or Art before time, and aborted 
Noble devices and deep-wrought healings,
Lest offence should arise. 

Heaven delivers on earth the Hour that cannot be
  thwarted,
Neither advanced, at the price of a world nor a soul,
  and its Prophet 
Comes through the blood of the vanguards who
  dreamed - too soon - it had sounded.
