Thomas Brooks was born in 1608. He entered Emmanuel College, Cambridge, in 1625, where such New England Puritans as Thomas Hooker, John Cotton, and Thomas Shepard were also educated, but he appears to have left before graduating. Brooks was ordained as a preacher of the gospel in 1640 and became a chaplain to the parliamentary fleet, serving for some years at sea. That ministry is mentioned in some of his “sea-devotions” as well as his statement: “I have been some years at sea and through grace I can say that I would not exchange my sea experiences for England’s riches.”
