But after these poems came the period of his prose, the work which he supposed was the abiding work of his life. George William Curtis told a friend that our civil war changed his own literary style: "That roused me to see that I had no right to spend my life in literary leisure. I felt that I must throw myself into the struggle for freedom and the Union. I began to lecture and to write. The style took care of itself. But I fancy it is more solid than it was thirty years ago." That is what happened to Milton when the protectorate came.[32] It made his style more solid. He did not mean to live as a poet. He felt that his best energies were being put into his essays in defense of liberty, on the freedom of the press and on the justice of the beheading of Charles, in which service he sacrificed his sight. All of it is shot through with Scripture quotations and arguments, and some of it, at least, is in the very spirit of Scripture. The plea for larger freedom of divorce issued plainly from his own bitter experience; but his main argument roots in a few Bible texts taken out of their connection and urged with no shadow of question of their authority. Indeed, when he comes to his more religious essays, his heavy argument is that there should be no religion permitted in England which is not drawn directly from the Bible; which, therefore, he urges must be common property for all the people. There is a curious bit of evidence that the men of his own time did not realize his power as a poet. In Pierre Bayle's critical survey of the literature of the time, he calls Milton "the famous apologist for the execution of Charles I.," who "meddled in poetry and several of whose poems saw the light during his life or after his death!" For all that, Milton was only working on toward his real power, and his power was to be shown in his service to religion. His three great poems, in the order of their value, are, of course, "Paradise Lost," "Samson Agonistes," and "Paradise Regained." Whoever knows anything of Milton knows these three and knows they are Scriptural from first to last in phrase, in allusion, and, in part at least, in idea. There is not time for extended illustration. One instance may stand for all, which shall illustrate how Milton's mind was like a garden where the seeds of Scripture came to flower and fruit. He will take one phrase from the Bible and let it grow to a page in "Paradise Lost." Here is an illustration which comes readily to hand. In the Genesis it is said that "the spirit of God moved on the face of the waters." The verb suggests the idea of brooding. There is only one other possible reference (Psalm xxiv:2) which is included in this statement which Milton makes out of that brief word in the Genesis:
