I found myself a man encompassed with infirmities; the parting was like pulling the flesh from my bones.... Oh, the thoughts of the hardship I thought my poor blind one might go under would break my heart to pieces. Poor child, thought I, what sorrow thou art like to have for thy portion in this world; thou must be beaten, must beg, suffer hunger, cold, nakedness, and a thousand calamities, though I cannot now endure that the wind should blow upon thee.[169] And then, because he thinks always in parables and seeks out most curious texts of Scripture, he speaks of "the two milch kine that were to carry the ark of God into another country and leave their calves behind them." Poor cows, poor Bunyan! Such is the mind of this extraordinary man. With characteristic diligence Bunyan set to work in prison making shoe laces, and so earned a living for his family. His imprisonment lasted for nearly twelve years; but he saw his family frequently, and was for some time a regular preacher in the Baptist church in Bedford. Occasionally he even went about late at night, holding the proscribed meetings and increasing his hold upon the common people. The best result of this imprisonment was that it gave Bunyan long hours for the working of his peculiar mind and for study of his two only books, the King James Bible and Foxe's _Book of Martyrs_. The result of his study and meditation was _The Pilgrim's Progress_, which was probably written in prison, but which for some reason he did not publish till long after his release. The years which followed are the most interesting part of Bunyan's strange career. The publication of _Pilgrim's Progress_ in 1678 made him the most popular writer, as he was already the most popular preacher, in England. Books, tracts, sermons, nearly sixty works in all, came from his pen; and when one remembers his ignorance, his painfully slow writing, and his activity as an itinerant preacher, one can only marvel. His evangelistic journeys carried him often as far as London, and wherever he went crowds thronged to hear him. Scholars, bishops, statesmen went in secret to listen among the laborers, and came away wondering and silent. At Southwark the largest building could not contain the multitude of his hearers; and when he preached in London, thousands would gather in the cold dusk of the winter morning, before work began, and listen until he had made an end of speaking. "Bishop Bunyan" he was soon called on account of his missionary journeys and his enormous influence.
