Milton wrote "On His Blindness" in 1655 to reflect on losing his vision before reaching middle age. In three sentences: The poem uses extended metaphors comparing Milton's blindness to a spent light and his talents to buried money to question if God demands impossible tasks. However, the personified virtue of patience reassures him that God neither needs works nor gifts, and all can serve by accepting God's mild yoke or by waiting for his bidding, as a king requires both workers and those standing ready to assist.
