The mention of the poems of these years, the most delightful that Milton was ever to write, show that the six years spent at Horton were not entirely what he calls them, "a complete holiday spent in reading over the Greek and Latin writers." If he had never written another line, he had written enough by the time he left Horton to give him a place among the very greatest men who have practised the art of poetry in England. When he started abroad in 1638 he must have known, and his father too, that his daring choice had already justified itself. "You ask what I am about, what I am thinking of," he writes to his friend Diodati at the end of the Horton time; "why, with God's help, of immortality." It is the voice of a man who knows he has already done great things but counts them as nothing compared with what he is to do later on. Man proposes. In 1637 Milton was "pluming {43} his wings" for the very mightiest of poetic flights, for such a poem as would give full scope to his genius and place him among the great poets of the world. But in the result he actually wrote less poetry in the next twenty years than he had written in the previous five: less in quantity and far less in quality and importance. The first interruption was the completion of his elaborate education by a grand tour. His generous father, who was well-to-do rather than rich, had acquiesced in his not so far earning one penny for himself, and was now prepared to provide him with about a thousand pounds of our present money to enable him to go abroad for a year or two in comfortable style and with the attendance of a servant. Leaving England in the spring of 1638, he spent a few days in Paris, where he was civilly entertained by the famous Grotius, then Swedish Ambassador there, as well as by the English Ambassador, Lord Scudamore, but soon moved south, entering Italy by Nice and Genoa and arriving at Florence in August or September. There he spent two months, and was enthusiastically received by the various academies or clubs of men of letters which then flourished in Florence, one of whose still existing minute {44} books records that at its meeting on September the 16th a certain John Milton, an Englishman, read to the members a Latin hexameter poem showing great learning. There also he paid his famous visit to Galileo, now old and blind, and still a sort of nominal prisoner of the Inquisition, for the sin, as Milton says in the _Areopagitica_, of "thinking in Astronomy otherwise than the Franciscan and Dominican licensers thought." One may be sure that it was not merely the interest of the new theory about the motion of the earth which drew him back so often to that question in _Paradise Lost_. The blind astronomer, whose scientific heresies had placed him in some danger of the thumbscrew, must have been a very near and moving memory to the blind poet whose political and ecclesiastical heresies had so nearly brought him to the gallows.
