Blake, however, never attained to his teacher's proficiency; he learnt just enough to be able to formulate to himself the nature of the Greek genius, and to see it in relation to his own. "The Muses were the Daughters of Memory." The inspiration of the Bible was from a higher source than Memory. Memory is the indelible record of experience. Inspiration is always a breaking into experience to the creation of something new. Then only is the new creation handed over to Memory. Thus Inspiration feeds Memory, but is not its fruit. Imagination is the true instrument of Inspiration. When Blake saw all this clearly, he wrote in the Preface to _Milton_: "We do not want either Greek or Roman Models if we are just and true to our own Imaginations." Greek and Latin have their abiding place in Memory, and Blake was about to write fine things about Memory, which he calls the Halls of Los; but for himself they did not stimulate his imagination. To master them would add to his culture; but mere culture is always barren. Hayley's last attempt to teach Blake was in March 1805, the month in which Klopstock died. He translated parts of Klopstock's _Messiah_ aloud for Blake's benefit. Certain lines by Blake with big gaps have been preserved, which are hard for us to understand. The only thing we are quite sure about them is that they were written "after _too much_ Klopstock." There was one great name that held Hayley and Blake alike at this time. We know that Blake had always admired Milton's superb gifts, while he disliked his theology. Blake's special friends had also been preoccupied with Milton. Fuseli, for example, not only disagreed with Dr Johnson's strictures on the poet, but he had been inspired by his ardent imagination to paint a series of pictures illustrating the poet's works, and these had been on public view at a Milton Gallery opened on May 20th, 1799, and reopened March 21st, 1800. While Blake was with Hayley he naturally heard much of Milton from his latest biographer; and again their united interest in Cowper led them back to Milton, because of Cowper's cherished desire to edit Milton, with notes and translations.
