We are not then to look in the sonnets for latent traces of the suspended poetic creation They come from the other side of Milton's nature, the political, not the artistic. They are akin to the prose pamphlets, not to _Paradise Lost_. Just when the sonnets end, the composition of the epic was taken in hand. The last of the sonnets (23 in the ordinary numeration) was written in 1658, and it is to the same year that our authority, Aubrey-Phillips, refers his beginning to occupy himself with _Paradise Lost_. He had by this time settled the two points about which he had been long in doubt, the subject, and the form. Long before bringing himself to the point of composition, he had decided upon the Fall of man as subject, and upon the narrative, or epic, form, in preference to the dramatic. It is even possible that a few isolated passages of the poem, as it now stands, may have been written before. Of one such passage we know that it was written fifteen or sixteen years before 1658, and while he was still contemplating a drama. The lines are Satan's speech, _P. L._ iv. 32, beginning,-- O, thou that with surpassing glory crowned. These lines, Phillips says, his uncle recited to him, as forming the opening of his tragedy. They are modelled, as the classical reader will perceive, upon Euripides. Possibly they were not intended for the very first lines, since if Milton intended to follow the practice of his model, the lofty lyrical tone of this address should have been introduced by a prosaic matter-of-fact setting forth of the situation, as in the Euripidean prologue. There are other passages in the poem which have the air of being insititious in the place where they stand. The lines in Book iv, now in question, may reasonably be referred to 1640-42, the date of those leaves in the Trinity College MS., in which Milton has written down, with his own hand, various sketches of tragedies, which might possibly be adopted as his final choice.
