John Milton's Sonnet 19 is often referred to as On His Blindness or When I Consider How My Light Is Spent. It also is sometimes numbered 16, as it appeared in the publication Poems etc. upon several Occasions of 1673.

The sonnet deals with the idea of someone being useless (unable to work) in the eyes of God, unable to fulfill their ambition (as a writer in Milton's case) because of physical incapacity (blindness), which could lead to spiritual downfall.

But in the final reckoning, it is faith and not labour which counts. God is still God—to those who work and for those who do not.

In many respects, it is a straightforward Petrarchan sonnet of 14 lines, with an octet and a sestet. But the rhyme scheme of abbaabbacdecde is a little bit different than the traditional Petrarchan rhyme scheme (abbacddcefgefg).

  • The octet (first eight lines) is a thoughtful reflection on blindness and personal frustration, the speaker aware of his God-given skill, to write an epic, which blindness will undermine.
  • The sestet (the last six lines) focuses on the patience needed and perspective gained with regards to God, the speaker's Maker. The speaker accepts his blindness. God is great; even those who are not creative initiators are part of the divine whole.
  • Reading through, there is a sense of humility in the face of such a fate, the speaker asking questions, self-referencing to an extent, about his position relative to God.
  • Some scholars have noted a 'servant before master' situation, the speaker accepting of blindness but wanting to put it in perspective by first questioning, then answering. There is no self-pitying cry of 'Why me?'

Overall then, this sonnet is a positive reminder of the inclusive nature of the divine. Milton's blindness, though frustrating, didn't stop him contributing to society and to the cause he believed in. He may have doubted his relevance to God (by questioning), but he concludes that, in the end, all serve him.

It has become one of Milton's most popular sonnets because many feel it deals with Milton's own blindness, the onset of which began sometime before the early 1650s, when the sonnet was penned. This was a time of political turmoil in England, the civil war resulting in the execution of the king, Charles I, and power being given to Oliver Cromwell and the republicans, Milton among them.

Milton's literary talents were put to good use. He wrote political documents in support of the republican cause, attacking royalist claims. He was already blind in one eye when he wrote, in the Second Defense:

'the choice lay before me between dereliction of a supreme duty and loss of eyesight; in such a case I could not listen to the physician, not if Esculapius himself had spoken from his sanctuary; I could not but obey that inward monitor, I know not what, that spake to me from heaven. I considered with myself that many had purchased less good with worse iII, as they who give their lives to reap only glory, and I thereupon concluded to employ the little remaining eyesight I was to enjoy in doing this, the greatest service to the common weal it was in my power to render.'

'My often thought is,' he writes to Leonard Philaras, 1654, 'that since to all of us are decreed many days of darkness, as saith the Wise Man, Eccles. 11, 8, my dark thus far, by the singular favour of Providence, hath been much tolerable than that dark of the grave, passed as it hath been amid leisure and study, cheered by the visits and conversation of friends.'
