These we call Merchants of Light. F. Bacon (1561-1626), New Atlantis. First, M. de Montaigne.—When Montaigne found himself feeling old and ill, in 1580, he made up his mind to try the baths of Germany and Italy. So he set out; and returned in 1581. And sometimes the baths did him good and sometimes they made no difference; but the journeying never failed to do what the baths were meant for. He always, he says, found forgetfulness of his age and infirmities in travelling. However restless at night, he was alert in the morning, if the morning meant starting for somewhere fresh. Compared with Montaigne at home, Montaigne abroad never got tired or fretful; always in good spirits, always interested in everything, and ready for a talk with the first man he met.
