In the midst of his heavy official business and pamphleteering, Milton, whose sight had been weak from childhood, became totally blind. From then on, he had to carry on his work through secretaries, one of whom was Andrew Marvell. Mary Powell returned to Milton in 1645 but died in 1652 after she had borne him three daughters. He married Catharine Woodcock in 1656, and she died two years later. She is the subject of one of his most famous sonnets, beginning, "Methought I saw my late espoused saint." In 1663 he married Elizabeth Minshull, who survived him. Milton supported the Commonwealth to the very end. After the Restoration (1660) he was forced into hiding for a time, and some of his books were burned. He was included in the general amnesty, however, and lived quietly thereafter.
