The "Instructions for Writing History" was probably one of the earliest pieces written by him after Lucian had settled down at Samosata to the free use of his pen, and it has been usually regarded as his best critical work. With ridicule of the affectations of historians whose names and whose books have passed into oblivion, he joins sound doctrine upon sincerity of style. "Nothing is lasting that is feigned," said Ben Jonson; "it will have another face ere long." Long after Lucian's day an artificial dignity, accorded specially to work of the historian, bound him by its conventions to an artificial style. He used, as Johnson said of Dr. Robertson, "too big words and too many of them." But that was said by Johnson in his latter days, with admission of like fault in the convention to which he had once conformed: "If Robertson's style is bad, that is to say, too big words and too many of them, I am afraid he caught it of me." Lucian would have dealt as mercilessly with that later style as Archibald Campbell, ship's purser and son of an Edinburgh Professor, who used the form of one of Lucian's dialogues, "Lexiphanes," for an assault of ridicule upon pretentious sentence-making, and helped a little to get rid of it. Lucian laughed in his day at small imitators of the manner of Thucydides, as he would laugh now at the small imitators of the manner of Macaulay. He bade the historian first get sure facts, then tell them in due order, simply and without exaggeration or toil after fine writing; though he should aim not the less at an enduring grace given by Nature to the Art that does not stray from her, and simply speaks the highest truth it knows. The endeavour of small Greek historians to add interest to their work by magnifying the exploits of their countrymen, and piling wonder upon wonder, Lucian first condemned in his "Instructions for Writing History," and then caricatured in his "True History," wherein is contained the account of a trip to the moon, a piece which must have been enjoyed by Rabelais, which suggested to Cyrano de Bergerac his Voyages to the Moon and to the Sun, and insensibly contributed, perhaps, directly or through Bergerac, to the conception of "Gulliver's Travels." I have added the Icaro- Menippus, because that Dialogue describes another trip to the moon, though its satire is more especially directed against the philosophers. Menippus was born at Gadara in Coele-Syria, and from a slave he grew to be a Cynic philosopher, chiefly occupied with scornful jests on his neighbours, and a money-lender, who made large gains and killed himself when he was cheated of them all. He is said to have written thirteen pieces which are lost, but he has left his name in literature, preserved by important pieces that have taken the name of "Menippean Satire."
